摘　　要：针对水工岩质边坡,分析岩石力学实验参数样本数量,采用曲线拟合方法得到了不同岩石各力学参数概率密度方程。根据岩石力学参数,采用ABAQUS对边坡进行强度折减,同时对岩石抗剪强度参数进行正交实验,得到边坡安全系数概率分布情况,结合结构可靠度理论分析边坡的可靠度并最终确定了边坡的安全系数。结果表明文中边坡安全系数及可靠度分析方法可行,可为类似工程提供参考。In order to study a rockslope,the number of experimental parameters of rock mechanics was analyzed and curve fitting method was used to get probability density equation of the mechanical parameters of different rocks.According to the rock mechanics parameters,using ABAQUS strength reduction method and orthogonal experiment of shear strength parameter to analysis the probability distribution of slope safety factor,combined with structural reliability theory,the reliability of the slope and the safety factor of the slope were determined.The results show that this slope method for analyzing safety factor and reliability was correct,which can provide reference for similar projects.
