摘要：
Considering parameter uncertainty in rock mass stability analysis, the finite element analysis (FEA) model of plane failure slope is set up based on ABAQUS. The model is used to perform the numerical simulation of slope stable state, to acquire the data for adaptive neuro-fuzzy inference system (ANFIS) analysis. The model, on rock mass mechanics parameters and anti-slide and down slide forces, is established based on ANFIS; then the statistical. characteristic of anti-slide and down slide forces is obtained. The program to solve slope failure probability and reliability is compiled with Monte-Carlo and Matlab, and used to analyze the slope reliability of Xuefeng open pit in Hunan Province. The result manifests that this method can avoid compiling redundant FEA program, reduce computational time, and improve computational precision.
