Stability of Embankment Dams Following Reservoir Drawdown
… were established in the present study based on soil plasticity through the results of the laboratory-testing program and stability analyses for 11 embankment dams.

Controlling role of suction stress in the Atterberg limits
Soil plasticity and consistency are indicators of a soil’s strength and deformation as a function of water content. They are often treated as secondary concepts in geotechnical analysis, likely due to the arbitrary and empirical nature of their definitions—such as those associated with plastic and …

Effects of Mica On Soil Properties For Embankment Construction
… part of the highway construction process, and soils from borrow pits are often used to construct these structures. The soil from these borrow pits is often characterized as needed, on a project by project basis, and is tested for the properties necessary for embankment design. As the upstate of …

Finite deformation of particulate geomaterials: frictional and anisotropic Critical State elasto-plasticity
… constitutive modelling and large strain plasticity. Although focused on soil plasticity, this research has relevance to other areas, such as metal forming and bio-engineering. Initially the concepts of material and geometric non-linearity are reviewed. A general implicit backward Euler …

A new constitutive model for the finite element analysis of metal powder compaction
… found that a cap yield surface, often used in soil plasticity, best fitted the experimental data obtained from the aluminium powder. A model similar to that proposed by Watson was implemented in this thesis in an attempt to show that a cap yield surface is more accurate for modelling the …

Detection of expansive soils using remote sensing in Brits North-West Province South Africa
Expansive soils generally pose a significant geological hazard, which causes damage to civil infrastructure that could amount to billions of rand every year. Traditionally, expansive soils have been mapped and characterized using methods such as X-ray Diffraction (XRD) and standard engineering …

Electrochemical bonding and clay compression
Soil compression is a topic of increasing importance in the evaluation of foundation sites for the heavy, rigid structures being founded upon them. The first analytical approach to compressive behavior in soil was presented by Terzaghi in the 1920's. Since that time, his consolidation theory has …

The Role of Soil Stiffness in Reverse Fault Rupture Propagation
… flow was employed to study the plastic soil properties which affect the rate of surface fault rupture propagation in reverse events. These numerical simulations show a trend for soils with higher stiffness to have a higher rate of rupture propagation. Additionally the study shows the …
