Slope failure simulations with MPM

Abstract

The simulation of slope failures, including both failure initiation and development, has been modelled using the material point method (MPM). Numerical case studies involving various slope angles, heterogeneity and rainfall infiltration are presented. It is demonstrated that, by utilising a constitutive model which encompasses, in a simplified manner, both pre- and post-failure behaviour, the material point method is able to simulate commonly observed failure modes. This is a step towards being able to better quantify slope failure consequence and risk.
