On an energy-based criterion for defining slope failure considering spatially varying soil properties
Engineering Geology(2020)
摘要
•The characteristics of various forms of energy are studied using finite difference-based strength reduction method.•Both the spatial distribution and evolution of the energy with increasing strength reduction factors are analyzed.•The effects of cross-correlated random field soil properties on the energy characteristics are investigated.•The sudden change in gravitational potential energy, dissipated energy, and kinetic energy serves as a good sign of slope failure.•Two distinct mechanisms in the effects of strength reduction on the elastic strain energy are identified and discussed.
