<p>Using a software package that can be used for either three or two-dimensional (2D) slope stability analyses of the same model we analyse the stability of columns (3D) or slices (2D) overlying a shear failure surface. The failure surface can be any shape, ...

Locating the critical slip surface with the minimum factor of safety of a slope is a difficult NP type optimization problem. In recent years, some modern global optimization methods have been developed with success in treating various types of problems, but ...

Back-analysis of a landslide is performed to estimate the mobilized shear strength of the problematic layer. Back-analysis can be an effective procedure for estimating the mobilized shear strength because it avoids the problems associated with laboratory and ...

Drained residual shear strength is considered applicable for the analysis of slopes with a preexisting shear surface. Torsional ring and direct shear tests were performed to investigate the gain in strength, if any, along a preexisting shear surface with time. ...

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 ...

Pleistocene valley fills dominated by glaciolacustrine sediments commonly occur in southern British Columbia and northern Washington. The fills contain multiple glaciolacustrine units separated by glacial tills and outwash gravels reflecting multiple episodes ...

The largest landslides on the south coast of England are those associated with failure surfaces in montmorillonite-rich mudstones close to the base of the Gault Formation (mid Cretaceous). Those at Folkestone, Sussex (Trenter &amp; Warren, 1996), Ventnor, ...

The results of a series of physical model studies of the stability of jointed rock slopes carried out some years ago are described in this paper.

<p>Limit equilibrium (LE) methods have been commonly used to analyze stability of geosynthetic-reinforced slopes. LE methods assume a potential slip surface, the soils along this slip surface providing shear resistance, and geosynthetic reinforcement providing ...

The design of a Geosynthetic Reinforced Soil (GRS) wall for internal stability against pullout failure requires computing the reinforcement embedment length. Therefore, the location of failure plane is an important input for this design. The current FHWA MSE ...
