Geosynthetics, a versetile solution to challenges in geotechnical engineeringeSAT Journals
Abstract This paper focuses on the available state of knowledge in the field of soil improvement particularly by the use of geosynthetics. Geosynthetics have found an important place in geotechnical engineering problems i.e. foundation on soft soils, land slide control, sub grade stabilization, reinforced embankments over soft soils, erosion control (turf reinforcement, under rip rap), surface drainage etc. This paper gives an overview of geosynthetics from its historical development to latest trends in it. Index Terms: Geosynthetics,
A geotextile is typically defined as any permeable textile material used to increase soil stability, provide erosion control or aid in drainage. More simply put, if it is made of fabric and buried in the ground it is probably a geotextile. Geotextiles are a permeable synthetic material made of textile materials. They are usually made from polymers such as polyester or polypropylene.
Geotextiles are a permeable synthetic material made of textile materials. They are usually made from polymers such as polyester or polypropylene. The geotextiles are further prepared in three different categories;
Woven geotextile,
Non-woven geotextile.
Now a days Jute are also applied as geotextile.
Geotextiles are a kind of geosynthetic material that has become more and more popular over the past fifteen years. The material owes its success in more than 80 applications to a large extent to its resistance to biodegradation. Geotextiles are indeed textiles, however not in the traditional sense of the word. They are no natural materials like cotton, wool or silk. Geotextiles are synthetic fibers that can be made into a flexible, porous, nonwoven needlefelt fabric. They are porous to water flow, to a varying degree.

CW RADAR, FMCW RADAR, FMCW ALTIMETER, AND THEIR PARAMETERSveerababupersonal22
It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
3. Geosynthesis
• Planar product manufactured from polymeric material used
with soil, rock, earth, or other geotechnical engineering
related material as an integral part of a man-made project,
structure, or system.
These products have a wide range of applications and are
currently used in many civil, geotechnical, transportation,
geo environmental, hydraulic, and
private development applications
including roads, airfields, railroads, embankments, retaining
structures, reservoirs, canals, dams, erosion
control, sediment control, landfill liners, landfill
covers, mining, aquaculture and agriculture.
5. • A Geogrid is geosynthetic material used to reinforce soils and similar
materials. Geogrids are commonly used to reinforce retaining walls,
as well as sub bases or sub
They have open grid like configuration i.e. they have large aperture
between individual ribs.
They have Low strain and stretch about 2% under load
Strength is more that other common geotextiles
Function: Used exclusively for reinforcement soil's below roads or
structures.
6. APPLICATIONS OF GEO GRIDS
Load is distributed
Evenly After the
use of Geogrid
Geogrid used beneath the Road surface
7. Improvement of sub grade: The
sub grade, which is the most important
load bearing strata, is made solid and
strong by the geogrids.
Reinforcement of pavement
base: The thickness of base if increased
would increase the stiffness of base. The
reinforcement to a given base layer
would give adequate stiffening that helps
in reduction of thickness and time of
construction. This also helps in
increasing the life of the pavement.
8. • Usage of geogrids in retaining
wall construction is in the area of
soil backfills. Holding the soil
together will help in a stable
retaining wall construction. The
soil structural integrity can be
increased by reinforcing it by
geogrids. This help in confining
backfill as well as help in
distributing the loads.
9. GEOTEXTILES
• Geotextiles are permeable fabricswhich when used in association
with soil, have the ability to separate,filter, reinforce, protect, or
drain.
• Characteristics-
• Porous and allow flow of water through it.

Drainage.
12. GEONETS
• Geonets are also planar products.
• Consists of ribs in two directions.
• Apertures are of diamond shape.
• Thickness is larger than that of geogrids.
• Are also known as “geospacers”.
Geonets are made of stacked, crisscrossing
polymer strands that provide
in-plane drainage.
Two layers of strands are called “biplaner”.
Three layers are called “tri-planar”.
biplaner “tri-planar”.
13. APPLICATIONS
• Erosion control : ribs acts as small
check dams to slow down the
surface runoffs which decrease
erosion potential of water.
Drainage layers: water flows along
the geonets because of
largethickness.
14.
15. GEOMEMEBRANES
• A Geomembrane is very low
permeability synthetic membrane
barrier used to control fluid or gas
migration in a structure, or system.
• Thickness impervious plastic sheet
is 0.5mm to 3mmapproximately.
• Used as a fluid barrier in designing
drainage systems ,etc.
• Used as damp proofcourse in
floors, roofs etc.
18. Geo synthetic clays

depth of soil and transfer of load through
• Allow water through it.
• Used in slopes with soft sub-grade
• Used in erosion control in channels
22. GEOFOAMS
• Geofoam is manufactured into large lightweight
blocks by polymeric expansion process. They are
large but extremely light materials
• Low density/ high strength: Geofoam is1% to 2% the
density of soil with equal strength.
• Quick to install and can be installed during any type
of weather.
• If geofoam comes in contact with a petroleum
solvent, it will immediately turn into a glue-type
substance, making it unable to support any load.
• Untreated geofoam is a Fire hazard with gas filled
cells.
23. Applications
• Uses-
• within soil embankments built over
soft, weak soils;
• under roads, airfield pavements and
railway track systems subject to
• excessive freeze-thaw conditions.

26. Disadvantages
Long-term performance of the particular formulated resin being
used to make the geosynthetic must be assured by using proper
additives including antioxidants, ultraviolet screeners, and fillers.
The exposed lifetime of geosynthetics, being polymeric, is less
than unexposed as when they are soil backfilled.
Clogging or bioclogging of geotextiles, genets, geo pipe and/or
geo composites is a challenging design for certain soil types or
unusual situations. For example, loess soils, fine cohesion less silts,
highly turbid liquids,
Generally require specialized testing evaluations.
Handling, storage, and installation must be assured by careful
quality control and quality assurance.
27. LATESTTRENDS
INPRESENTTIME
• VACCUM CONSOLIDATIONS:Vacuum consolidation (or vacuum preloading) is a
soft soil improvement method that has been successfully used
by geotechnical engineers and specialists of ground improvement companies in
countries such as Australia, China, Korea ,etc.
• ENCASEDSTONECOLUMNS:Stone columns installed in very soft soils will have
very low lateral confinement: hence they undergo excessive bulging, leading to
undue settlement and limited load-carrying capacity. In these situations, the
strength and stiffness of the stone column can be enhanced by encasing the
individual stone columns with a suitable geosynthetic. The encasement improves
load transfer to deeper depths of soil.
• ELECTROKINECTICGEOSYNTHESIS: Electro kinetic geo synthetics (EKG)can be
achieved by combining the electro kinetic phenomena of electro-osmosis,
electrophoresis and associated electro kinetic functions such as electrolysis with
the traditional functions of geo synthetics of drainage, filtration, containment and
reinforcement.
