Paper Number: ISRM-IS-2000-045
... ABSTRACT: This paper describes a new technique for computing lower bound limit loads in anisotropic media under conditions of plane strain. Although limit analysis has been applied extensively to homogenous and isotropic soils, as well as soils with a variation of cohesion with direction...

... caused by an earthquake. In this study, an integrated planes elastic-plastic model for predicting the behavior of liquefiable sand under cyclic loading on the basis of sliding mechanisms and elastic behavior of particles has been presented. This model is implemented in a finite element program to solve...

Three-dimensional spectra are obtained as a function of two frequencies along the co-ordinate axes. The cross-sections of the spectrum are then investigated and the pattern...

The re-pressurisation of a fault triggered small shear movements, thus weakening the casing so that it could not withstand a decrease of internal pressure. Joints or planes of weakness with about ten centimetres spacing can also lead to instabilities...
