Abstract: The widely differing factors of safety obtained by strength reduction and load increase in the ultimate bearing capacity of foundations have been reexamined analytically. In most cases, factors of safety based on load ...

Abstract: The use of numerical methods such as finite elements to make accurate predictions of failure or collapse of geomaterials must utilize a suitable failure criterion that is able to represent the shear strength for all stress ...

Abstract: This paper will present stability analyses and charts to estimate the factor of safety (FS) for partially submerged undrained slopes with linearly increasing strength with depth and unlimited foundation depth. The problem ...

Abstract: Application of the effective stress principle in unsaturated geotechnical engineering problems often requires explicit knowledge of the stress acting on the soil skeleton due to suction pore water pressure. This stress is ...

Abstract: This paper shows that for perfect plasticity, the closest point projection method (CPPM) and the cutting plane algorithm (CPA) for return mapping are exactly equivalent for piecewise linear yield criteria under both ...

Abstract: Two well-known return mapping algorithms, the closest point projection method (CPPM) and the cutting plane algorithm (CPA), have been analyzed in detail in relation to two classical failure problems in geomechanics, namely, ...

Abstract: The paper discusses finite element models for predicting the elastic settlement of a strip footing on a variable soil. The paper then goes on to compare results obtained in a probabilistic settlement analysis using a ...

Abstract: This paper brings together random field generation and finite-element techniques to model steady seepage through a three-dimensional (3D) soil domain in which the permeability is randomly distributed in space. The analyses ...

Abstract: The existence of large hydraulic gradients in regions of an earth dam where fine-grained soils are inadequately filtered can sometimes lead to internal erosion and piping failure. This paper investigates the stochastic ...

Abstract: By modeling soil as a three-dimensional spatially random medium, the reliability of shallow foundations against serviceability limit state failure, in the form of excessive settlement and/or differential settlement, can ...
