Analysis for progressive failure of the Senise landslide based on Cosserat continuum model

摘要

Based on pressure-dependent elastoplastic Cosserat continuum model,progressive failure phe-nomena of the Senise slope occurred in the excavation processes,characterized by strain localization due tostrain softening,are numerically simulated. Numerical results indicate the inability of classical continuum modelin simulating the whole failure progress,while the capability and performance of Cosserat continuum model inkeeping the well-posedness of the boundary value problems with strain softening behavior incorporated and incompleting simulation of the whole failure progress.
