Among soil improvement techniques used to increase strength of loose and<br>medium-dense sand deposits are the dynamic means, such as vibrocompaction and blasting. Sands often exhibit a drop in cone penetration resistance immediately after the disturbance, ...

<p>Design of slopes and analysis of existing slopes subjected to seismic shaking are carried out routinely using approximations of plane strain and substitution of a quasi-static load for the seismic excitation. A three-dimensional
3D analysis of slopes ...

The kinematic approach of limit analysis is explored in three-dimensional
3D stability analysis of slopes. A formal derivation is first shown indicating that, in a general case, the approach yields an upper bound to the critical height of the slope or an ...

The influence of pore-water pressure and the pool water pressure on stability of submerged slopes was investigated using the kinematic approach of limit analysis. For soils with some cohesive component of strength, the critical pool level is slightly below ...

Three-dimensional (3D) limit analysis of stability of slopes is presented. Such analyses are not common, because of the difficulties in constructing three-dimen­sional mechanisms of failure in frictional soils. A class of admissible rotational mechanisms is ...

Fibre reinforcement is a technology to improve the strength of soils used as fill in geotechnical structures. The properties of the fibre-reinforced sand are anisotropic because of the distribution of orientation of the fibres, which is characterised by a ...

This paper describes the potential of wireless sensing networks to improve geotechnical field monitoring and the use of wireless sensors in two on-going geotechnical research projects. Both studies are Network for Earthquake Engineering Simulation Research ...

A method is presented for calculations of irreversible displacements of multiblock structures subjected to seismic excitation. Use is made of the kinematic approach of limit analysis. To make the analysis tractable a hodograph representing distribution of ...

The behavior of soil retaining structures during earthquakes is investigated. Seismic excitation imparts inertial forces to the soil retaining system, and, once the seismic acceleration reaches the yield level, the structure exhibits permanent displacements. ...

<p>Soil reinforcement is a practical solution to construction over weak soils. Application of the kinematic approach of limit analysis to reinforced soil is reviewed, both for traditional reinforcement with strips or sheets of geosynthetic material and for ...
