Abstract

Stability of high cutting slope concerns safety pass of road at the bottom of slope and has relationship with security and stability of buildings on the top of slope. On the basis of ANSYS finite element strength reduction method, this paper does elastoplastic nonlinear and large deformation geometric nonlinear analysis on slope. In terms of three-dimensional deformation of space, this paper utilizes Drucker -Prager elastoplastic model in finite element analysis and uses full N-R in large deformation analysis. Analyses on three-dimensional homogeneous high cutting slope show that three-dimensional slope model established through finite element strength reduction method could visually simulate the process of slope becoming unstable with increasing of reduction coefficient, in which better safety coefficient of slope could also be acquired. The utilization of strength reduction method in analyzing slope stability not only overcomes assumed slide of limit equilibrium method but also intuitively acquires sliding tendency and practical plastic sliding area of slope, which provides effective way for stability analysis on high cutting slope after excavation.
