On the estimation of scale of fluctuation in geostatistics
Describing how soil properties vary spatially is of particular importance in stochastic analyses of geotechnical problems, because spatial variability has a significant influence on local materialExpand

Influence of heterogeneity on the reliability and failure of a long 3D slope
Abstract The influence of heterogeneity of undrained shear strength on the performance of a long slope cut in clay is investigated. Random field theory is used to model the heterogeneity and finiteExpand

Development of an implicit material point method for geotechnical applications
Abstract An implicit material point method (MPM), a variant of the finite element method (FEM), is presented in this paper. The key feature of MPM is that the spatial discretisation uses a set ofExpand

Investigation of retrogressive and progressive slope failure mechanisms using the material point method
Abstract Retrogressive and progressive slope failures are a dynamic process, in the sense that they involve a progressively changing scenario. This paper uses the contemporary material point methodExpand

A stochastic approach to rainfall-induced slope failure
This paper considers the influence of spatial variability of soil properties on the stability of an unsaturated soil slope during and antecedent to a rainfall event. With water tending to follow aExpand

Influence of heterogeneity on 3D slope reliability and failure consequence
Abstract This paper investigates the influence of heterogeneity of undrained shear strength on the reliability of, and risk posed by, a long slope cut in clay, for different depths of foundationExpand

Uncertainty reduction and sampling efficiency in slope designs using 3D conditional random fields
A method of combining 3D Kriging for geotechnical sampling schemes with an existing random field generator is presented and validated. Conditional random fields of soil heterogeneity are then linkedExpand
