This document discusses finding a suitable correlation between the California Bearing Ratio (CBR) and different index properties for high plastic soil. It reviews existing correlations that have been proposed between CBR and simple field/laboratory tests like the dynamic cone penetrometer (DCP) test and Clegg Impact Value (CIV) test. The goal is to develop a framework for predicting CBR from percentage finer and plasticity index tests, which are simpler and less time-consuming than the CBR test itself. The proposed correlation will be established through graphical analysis of a large number of test results on soil samples collected from different sites in India.

IRJET- Prediction of Cbr Value from Index Properties Of SoilIRJET Journal
This document presents a study that aims to develop models for predicting the California Bearing Ratio (CBR) value of soil from index properties that are quicker to determine than the standard CBR test. The CBR test takes 4 days to complete but engineers need a quicker assessment of soil strength. The researchers collected soil samples and conducted tests like sieve analysis, Atterberg limits, standard Proctor, and CBR to determine properties like liquid limit, plastic limit, optimum moisture content, and maximum dry density. Correlations between CBR and individual properties showed varying strengths. Multiple linear regression analysis was then used to develop prediction models incorporating several properties. The models will help engineers assess soil strength more rapidly.

Abstract
Static and dynamic cone penetration tests are widely used in Foundation engineering for measuring the penetration resistance of the
ground and for relating it to the degree of compaction and safe bearing capacity of soils. In Highway Engineering, Pavement
Dynamic Cone Penetrometer (DCP) is used for rapid in-situ strength evaluation of subgrade and other unbound pavement layers. In
the present studies, an attempt has been made to identify the strength and thickness of different pavement layers of newly constructed
low volume roads in the State of Karnataka, India using dynamic cone penetration studies and was compared with actual
measurements at the site. The evaluation of pavement test stretches was made for a period of two years, and changes in penetration
resistance of different pavement layers were measured. A Software was used to analyze the DCP data and to correlate with field
observation. The results have favoured the possibility of using dynamic cone penetrometer as a quality control and pavement
monitoring tool for low volume roads, eliminating the need for a Benkelman beam or a falling weight deflectometer.

Dynamic Cone Penetrometer Value and California Bearing Ratio RelationshipIRJET Journal
This document discusses research into the relationship between Dynamic Cone Penetrometer (DCPT) values and California Bearing Ratio (CBR) values for different soils. The researchers conducted DCPT and CBR tests on clayey, sandy, and silty soils with varying moisture contents and compaction densities. Previous studies found direct linear relationships between DCPT and CBR values that depend on soil properties. The goal of this study is to determine the DCPT-CBR relationship for different soils and examine the effect of moisture and compaction. Establishing a reliable DCPT-CBR correlation could provide a quicker and cheaper way to estimate soil strength for pavement design.

Correlation between cbr and index propertys of soilRAJESH JAIN
This document discusses correlations between the California Bearing Ratio (CBR) and index properties of soil. It examines several existing correlations between CBR and properties like liquid limit, plastic limit, and maximum dry density. The authors analyze data from previous studies to compare predicted CBR values from two correlations to experimentally measured CBR values. They find that one correlation works better for clayey soils but overestimates CBR for highly plastic clays, while the other correlation predicts lower CBR values than measured across soil types. The authors conclude that the correlations show some agreement with tests for low plasticity clays but need improvement to reliably predict CBR from simple soil properties.
The document presents the results of a study that used linear regression to correlate index properties and California bearing ratio (CBR) values of lateritic soil samples collected from eight borrow pits in Osogbo, Nigeria. Laboratory tests on the samples found good correlations between CBR and properties like grain size, liquid limit, plastic limit, and maximum dry density. Regression equations were developed to estimate CBR values from index properties for preliminary assessments, though actual CBR tests are still needed given the heterogeneous nature of lateritic soils. The CBR values ranged from 64-85% unsoaked and 26-33% soaked. Most samples met specifications for subgrade, sub-base, and base materials, except two had lower soaked CBR

This document presents an experimental study that correlates test results from the plate bearing test (PBT), unconfined compressive strength (UCS) test, and California bearing ratio (CBR) test with results from the dynamic cone penetrometer (DCP) test on various soils under soaked conditions. Soil samples from different locations in Gujarat, India were tested for liquid limit, plastic limit, CBR, PBT, UCS, and DCP at their maximum dry densities achieved through modified proctor compaction in a soaked state. Empirical correlations between the test results were established using linear regression to develop formulations that can be used to estimate time-consuming strength parameters from rapid DCP tests.

This document summarizes a study on the variation of strength in cohesive soil with moisture content and time. Standard Proctor compaction tests were conducted on a silty clayey soil to determine its maximum dry density and optimum moisture content. Unconfined compressive strength tests were then performed on soil samples compacted at different moisture contents (ranging from 8.6% to 14.6%), and cured for different time periods from 0 to 30 days. The results showed that unconfined compressive strength and initial tangent modulus decreased with increasing moisture content, but increased with curing time, for all moisture contents tested. The study aims to understand how the strength and deformation properties of subgrade soils used in road construction can vary due to

This document summarizes an analytical study on how the natural frequency of a single pile foundation varies with soil-pile interaction effects. It presents the theoretical formulation for calculating the depth of fixity and natural frequency of a pile based on the soil modulus and pile diameter. A finite difference method and MATLAB code were used to model the soil-pile system and conduct a parametric study. The results show that the natural frequency non-linearly decreases with lower soil modulus and smaller pile diameter. An equation was developed through regression analysis to predict the natural frequency based on the soil and pile properties. Understanding how natural frequency varies with soil-pile interaction is important for designing foundations subjected to dynamic loads.
This document presents a mathematical approach to simulate soil behavior under shallow compaction. The approach aims to estimate property improvements of soil under compaction and develop equations to design compaction procedures. It involves correlating soil properties to dry unit weight, calculating contact stresses from compaction equipment, and estimating property changes after each compactor pass by updating soil properties. Case studies showed good matches between the proposed approach and field measurements. Equations were developed to calculate minimum equipment characteristics, lift thickness, and passes needed to achieve desired soil properties.
An Experimental Study on strength behavior of Pavement using jute geo textile IJERA Editor
This experimental investigation studies the benefits of reinforcing the various sub grade soils in flexible pavement. Three types of soils A, B and C and a particular type of Jute geo textile material were selected for the study. Fundamental properties of soils like specific gravity, liquid limit, plastic limit and optimum moisture content were determined on unreinforced soils; California Bearing Ratio (CBR) test and Unconfined Compression (UCC) Strength test were also conducted on unreinforced and reinforced soils. The optimum quantity of jute geo textile was arrived based on the results from CBR test, other parameters such as modulus of elasticity and failure stress were ascertained from the results of UCC test. Using the optimum geo textile content, the thickness of pavement required over the three types of sub grade soils with and without reinforcement was determined based on the guidelines specified in IRC 37-2001. A comparative analysis was carried out to identify the economy in the material due to the effect of reinforcing the soils with jute geo textile. Subsequently cost benefit analysis of reinforced and unreinforced pavement was also done to ascertain the economic viability of fibre material. From the result analysis it was observed there is a significant material save of about 25% per every km of pavement

This document presents a study that developed empirical equations to predict the soaked CBR value of lean clay soils based on index properties, dry density, and unsoaked CBR values. Laboratory tests were conducted on soil samples collected from an existing flexible pavement, which identified the soil as lean clay. Soaked and unsoaked CBR tests were performed at different densities. Three equations were formulated: 1) Using index properties and compaction characteristics to predict soaked CBR, 2) Relating dry density to soaked CBR, and 3) Relating unsoaked CBR to soaked CBR over a range of dry densities. These equations can be used to predict soaked CBR for lean clay subgrade soils.
Investigation of Geotechnical Properties of a Lateritic Soil with Saw Dust AshIOSR Journals
This document investigates the use of saw dust ash (SDA) as a stabilizing agent for an A-7-6 lateritic soil. Tests were conducted on mixtures of the soil with 2%, 6%, 8%, 12%, 16%, and 20% SDA by weight. Results showed the liquid limit and plasticity index decreased with increasing SDA content up to 12%, while maximum dry density decreased and optimum moisture content increased. Unconfined compressive strength initially decreased then increased up to a maximum of 164.2 kPa at 16% SDA, around 4 times the strength of the untreated soil. The 12% SDA mixture produced strengths of 118.5 kPa, a plasticity index of 11.6

IRJET- Study of Variation in Bearing Capacity with Respect to Degree of Satur...IRJET Journal
This study examined how the bearing capacity of soil is affected by the degree of saturation. Tests were conducted on soil samples from 5 sites to determine properties like moisture content, density, grain size, cohesion, and friction angle. Triaxial tests under dry, saturated, and field conditions were used to establish relationships between saturation and shear strength. Bearing capacity was calculated using Terzaghi's equation for a square footing. Results showed that bearing capacity decreases with increasing saturation as friction angle reduces, despite increases in cohesion and density. An equation was proposed relating bearing capacity and degree of saturation. The study concluded saturation significantly impacts bearing capacity in coarse-grained soils due to effects on friction angle.

Disturbed soil samples were collected from eight locations in Jabalpur, India and tested to determine CBR, optimum moisture content, maximum dry density, and particle size distribution. Simple and multiple linear regression analyses were used to develop correlations between CBR and properties like OMC, MDD, and coefficient of uniformity. A multiple regression equation was developed that could predict CBR with 97.2% accuracy based on OMC, MDD, D60, and D30.

This document summarizes the results of an experimental study on the effect of roughness of the base of a rectangular combined footing on its ultimate bearing capacity and settlement in cohesive soil. Laboratory tests were conducted on model footings placed in a steel tank filled with locally sourced cohesive soil. Tests were performed with footing bases that were smooth and rough. The tests measured settlement under increasing loads. The results showed that rough footing bases experienced less settlement than smooth bases under the same loads, indicating that roughness improves a footing's bearing capacity and reduces settlement in cohesive soils. Prior research that found soil confinement around footings improves bearing capacity in granular soils is also cited.

Predicting Resilient Modulus of Clayey Subgrade Soils by Means of Cone Penetr...Pouyan Fakharian
Resilient modulus (Mr) of subgrade soils is considered as one of the most important factors for designing flexible pavements using empirical methods as well as mechanistic-empirical methods. The resilient modulus is commonly measured by a dynamic triaxial loading test, which is complex and expensive. In this research, back-propagation artificial neural network method has been employed to model the resilient modulus of clayey subgrade soils based on the results of the cone penetration test. The prediction of the resilient modulus of clayey subgrade soil can be possible through the developed neural network based on the parameters of the cone tip resistance (qc), sleeve friction (fs), moisture content (w), and dry density (γd). The results of the present study show that the coefficients of determination (R2) for training and testing sets are 0.9837 and 0.9757, respectively. According to the sensitivity analysis results, the moisture content is the least important parameter to predict the resilient modulus of clayey subgrade soils, while the importance of other parameters is almost the same. In this study, the effect of different parameters on the resilient modulus of clayey subgrade soil was evaluated using parametric analysis and it was found that with increasing the cone tip resistance (qc), the sleeve friction (fs) and the dry density (γd) and also with decreasing the moisture content (w) of soils, the resilient modulus of clayey subgrade soils increases.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
