摘要；针对岩质边坡工程稳定性分析中参数的不确定性，基于ABAQUA建立了平面破坏型边坡有限元分析模型。并用该
模型进行了边坡稳定状态的数值模拟，以获得进行ANFIS分析的数据。同时基于自适应神经模糊推理系统建立了岩体力学
参数与边坡抗滑力和下滑力的映射模型，分析得到抗滑力和下滑力的统计特征。根据蒙特卡罗模拟方法用MATLAB语言编
写了求解边坡的破坏概率和可靠度的计算程序，对湖南雪峰水泥原料矿山的露天矿边坡进行可靠度分析。研究结果表明，该
方法具有避免编写冗长的有限元计算程序、节省机时、计算精度高的优点。

Abstract：Considering parameter uncertainty in rock mass stability analysis，the finite element analysis(FEA)modd 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栅S；then the statistical．charactedstic of anti-slide and down slide forces is obtained．nIe
program to solve slope failure probabili哆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 compu
