Large deformation failure analysis of slopes using the smoothed particle finite element method

Abstract

Slope instability and landslides can be catastrophic events leading to loss of lives and properties. To prevent and assess the risks of slope failures, it is often desired that the dynamic process of the slope failure can be simulated, which is difficult with the classic Finite Element Method (FEM). In this study, the smoothed particle finite element method is developed based on the popular and efficient FEM. A numerical example with a slope model is employed to demonstrate the capacity of the proposed approach. An elastoplastic material model based on the Mohr-Coulomb yield criterion is used. The run out distance and failure mass is recorded which paves a way of being able to better quantify slope failure consequence and risk.
