The document summarizes the rockfall hazard rating and proposed mitigation plans for several rock cuts along Highway 63 between Rolla and Vienna, MO. It details using two different rating systems to evaluate the sites, with Site E scoring the highest risk. Three potential mitigation designs are proposed for Site E - various configurations of gabion walls, mesh draping over the slope, and limited excavation. A full-slope mesh draping design is recommended as the most cost-effective option that requires little maintenance and provides adequate protection.

Ground Improvement by Vibro Stone Columns
Vibro replacement stone column is one of the widely used soil improvement technique to improve the settlement characteristics, bearing capacity and mitigate the liquefaction issues of the soft soil. In this paper, improvement of the settlement characteristics of the soft soil is considered for the analysis based on the available case histories. A settlement estimation method proposed by Preibe (1995) is verified quantitatively. Finally, an analytical solution for settlement of soft ground for the stone column design is proposed. The proposed method of calculating settlement is based on the basic concept of composite material and soil mechanics. However, the result of this preliminary work is yet to validate numerically and in the field. Detailed research in future is necessary to check its validity and applicability
Rock mechanics
Rock mechanics focuses on studying the properties and behavior of intact rock and rock masses. Testing of intact rock samples involves destructive strength tests like uniaxial compression and triaxial tests as well as nondestructive tests like Schmidt hammer and sonic wave propagation. The compressive strength test is widely used in rock engineering to determine parameters like the Young's modulus. The complete stress-strain curve obtained from compression testing provides information on the rock's strength, stiffness and failure behavior. Other tests like point load and Brazilian tests are also used to indirectly measure the tensile strength of rock samples.
SLOPE STABILITY AND FAILURE
This document discusses slope stability and failure in open pit mines. It notes that as mining depths increase, slope design becomes more important for economic reasons. Slope stability problems can be either gross or local failures. Factors that affect stability include slope geometry, geology, groundwater, lithology, dynamic forces, and mining methods. Common failure types are planar, wedge, circular, and toppling. Slope stability is assessed using limit equilibrium methods or numerical modeling techniques. Numerical models divide the rock mass into zones to simulate complex slope behavior.

Behaviour of Single Pile in Reinforced Slope Subjected to Inclined Load
This document summarizes an experimental investigation into the behavior of single piles in reinforced slopes subjected to inclined loading. Model tests were conducted with piles of varying length (10D and 20D) located near a 1V:2H sandy slope reinforced with layers of geogrid. The lateral load capacity of the piles was evaluated by applying loads laterally and at inclinations of 15° and 30°. The load capacity was found to increase with load inclination, pile length, number of geogrid layers, and distance from the slope crest. Load-deflection curves and ultimate lateral load capacities are presented for piles under different test conditions. The results provide insight into pile response based on parameters like reinforced slope design and loading angle.

The document discusses the foundation engineering assessment for installing the world's largest jack-up rig offshore Norway. Based on site investigations, the soil conditions varied across the site and consisted of bedrock overlaid by soft silt/clay and a shallow sand layer. Conventional and finite element analyses proposed constructing sand banks to provide a stable foundation. Three-dimensional finite element modeling of the integrated jack-up structure, skirted spudcan foundations, and soil was used to determine the optimal sand bank geometry. The modeling showed structural forces would remain acceptable during installation, preloading, and storm conditions. The rig was successfully installed, validating the engineering predictions.
Circular failure
This document summarizes a case study of a slope failure that occurred on the Kimola Canal in Finland in 1965. The slope failure involved 90,000 cubic meters of clay sliding into the canal. Researchers analyzed the geotechnical conditions and concluded that the failure was caused by redistribution of excess pore pressures after excavation. New analyses using finite element modeling and measured pore pressure data found a factor of safety close to 1, consistent with the failure. The slope failure highlighted issues with assuming undrained strength parameters for design, as effective stress analysis better explained the failure. Inhomogeneity and anisotropy in the clay properties likely contributed to the upward extension of the failure surface.

Day 2 Presentation: Kinematic Analysis
This document discusses rock slope failures and kinematic analysis. It provides examples of different types of slope failures including planar, wedge, and toppling failures. The key cause of these failures is movement along discontinuities in the rock mass such as bedding planes, faults, and shear zones. Kinematic analysis uses stereonet plots of discontinuity orientations to determine if slopes are prone to planar, wedge, or toppling failures based on the orientation criteria for each failure type. Field measurements of discontinuity data from outcrops can be input to identify potential failure planes.
Analysis and Design Aspects of Support Measures of Main Caverns of Karuma Hyd...
The Power house complex of Karuma Hydropower project comprises three main caverns i.e Power house, Transformer Hall and Tailrace surge gallery set at a depth of about 80m in mainly granitic gneiss rock medium. The cavern has been oriented in a N141° direction based on engineering considerations. The principle stress direction is also found nearly parallel to the axis of the caverns and thus the present orientation satisfies both engineering and geotechnical criteria. The support by way of rock anchors and SFRS/ Plain shotcrete has been provided based on analysis using phase 2 software. The underground caverns lie in low geostress field and therefore numerical simulation of excavation of these caverns were done to understand the rock mass behavior during excavation and thus help in design of excavation sequence and rock support. The excavation of all three caverns has since been completed and concrete works are in progress. This paper sums up the 3D simulation analysis of the rock medium and the proposed rock support system for the three caverns.

Chapter6
The document discusses the use of the RMi rock mass characterization system for designing rock support in underground excavations. It begins by outlining the goals of underground excavation design and some current methods for stability analysis and rock support estimation. These include classification systems, ground-support interaction analysis using Fenner-Pacher curves, and key block analysis. The chapter then reviews factors influencing stability, defines key terms, and describes various modes of failure in underground openings including block failures, overstressing of intact rock or jointed materials, and special considerations for faults and weakness zones.
Slope stability
There are several types of slope failures that can occur in open pit mines. Plane failures occur along a planar discontinuity when the dip of the discontinuity is less than the slope angle. Wedge failures result from the intersection of two discontinuity sets dipping out of the slope. Circular failures have a curved failure surface and generally occur in weak soils or rocks. Toppling failures involve the overturning of rock columns formed by steeply dipping discontinuities. Slope stability is influenced by factors that increase shear stress, like excavation, or decrease shear strength, such as weathering. Accurately predicting slope failures is important for safety in open pit mining.
Slope stability question answers
The document discusses various factors that affect slope stability and methods to determine slope stability. It addresses how gravitational forces, water, earthquake activity, slope angle, and rock structures can impact stability. Specific triggers for landslides include rainfall, erosion, construction activities, and earthquakes. Slope stability is determined by calculating the factor of safety, which compares resisting and driving shear forces based on a slope's cohesion, internal friction, and other properties. A factor of safety below 1 indicates a slope is unstable.

Retaining structures help ensure slope stability but are difficult to construct on moving slopes. Major disasters in India include earthquakes, floods, droughts, and cyclones that have caused thousands of deaths and widespread damage.

Foundation Design requires the knowledge of the behavior of the structure supported by the foundation as well as that of soil or rock that furnishes the ultimate support.
The super structure, foundation and soil or rock must act together and each must posses its unique serviceability and safety in the interactive system
The soil or rock may provide adequate safety of the foundation against failure, detrimental settlement may occur prior to any collapse. Which may be analogous to beam or truss in super structure but does not meet the serviceability(Deflection) criteria
The super structure designs are controlled by the strength of material such as shear strength ,compressive strength and tensile strength but deformations governs the design of foundation.
3 Secured Drapery 2008
The document discusses tests conducted on rockfall protection systems using secured drapery panels. The tests were performed on 3x3 meter square panels to evaluate the stiffness of the revetment system and load transferred to anchors. Stiffness refers to the force needed to deform the panel when a perpendicular force is applied. Various panel designs were tested and results showed designs with horizontal cables and deformable knots performed best. Research concluded mesh systems with high stiffness can better control rockfall instability by reacting to movement before less stiff systems.

1. The document analyzes embankments supported by stone columns with and without geosynthetic encasement using finite element modeling.
2. Parameters like stone column diameter, length-to-diameter ratio, encasement stiffness, and undrained shear strength were varied to analyze their effects.
3. The results show that encasing stone columns with geosynthetics significantly reduces settlement and lateral displacement of the embankment compared to unencased stone columns. Increasing stone column diameter and undrained shear strength also reduces displacement.
Applications of Vane Shear Test in Geotechnical soil investigations
The document discusses the results of vane shear tests conducted on soil samples from a site for a proposed 40 km highway near a riverbank. The test results show undrained shear strengths (Cu) below 90 kPa, indicating the need for ground improvement. Recommendations include using geotextiles to separate weak subgrade soils from pavement layers, improving the subgrade quality through compaction or adding aggregates/additives, using geogrid reinforcement in the subgrade and base course, and placing geogrids and concrete on embankment slopes for stability.

This document discusses the evolution of concrete pavement design from the 1960s-1980s to present day designs. It begins by outlining some of the deficiencies of older designs including underestimating traffic loads, not considering climate factors, and experiencing high rates of faulting and cracking. It then describes how current designs have improved through developing theoretical distress models, conducting extensive field performance testing, and creating a mechanistic-empirical design procedure that reliably predicts field performance. Examples are given of modern designs that provide 40-100 year service life through improved considerations of traffic, climate, materials, and structure.Analysis of tunnel in weak rock
This presentation is about the properties of rockmass around tunnel in weak rock, before and after excavation.

This document describes an aluminum fuel that has a higher energy density than lithium-ion batteries and gasoline. The fuel reacts with water to produce hydrogen and heat through a chemical treatment process that is fast, wastes little aluminum, and achieves high reaction completion and aluminum content. The fuel treatment involves creating micro-galvanic cells in the aluminum grain structure to split water molecules and produce energy, offering economic viability comparable to gasoline with recoverable and reusable materials.

This document provides guidance on techniques for acquiring sedimentological data from clastic rocks, including sedimentary logging. The key points covered include:
1. The essential equipment needed for sedimentary logging includes a notebook, measuring tools, and grain size comparator.
2. An important initial step is selecting a representative logging route that is physically accessible and shows continuity.
3. Descriptions of lithological units like mudstones and sandstones involve semi-quantitative scales for aspects like bioturbation.
4. Logs are plotted using scales for lithology, thickness, and grain size. Sedimentary structures are coded onto the log.
5. Example logs and exercises are provided to demonstrate plotting techniques and

The document summarizes the design and construction of the foundations for the Rion Antirion Bridge in Greece. An innovative foundation concept was adopted using steel tubular piles driven into the seabed to reinforce the soil, with a gravel layer between the piles and the concrete caisson foundation. This concept provided seismic capacity and minimized differential settlement risks. Close cooperation between designers, contractors, and reviewers was essential to developing and implementing this challenging foundation solution.
Dfi2005 pecker
The Rion Antirion bridge in Greece connects the Peloponnese peninsula to the mainland across the Gulf of Corinth. Its foundations had to withstand severe environmental conditions including weak soils, earthquakes up to magnitude 7.0, and long-term tectonic movements. The innovative foundation concept adopted reinforced the natural ground with steel tubular piles and included a gravel layer between the piles and foundation raft. This provided capacity to resist the large seismic forces while minimizing differential settlement hazards. Extensive site investigations characterized the poor soil properties to ensure compatible design of seismic demand and foundation capacity.
