摘　　要：以雅砻江某边坡为例,对边坡岩土物理力学参数采用蒙特卡洛抽样,并且自编抽样数据与GEOSLOPE软件接入程序,借助GEOSLOPE软件逐次计算安全系数,得出安全系数均值、方差、失稳概率,同时将计算结果与GEOSLOPE软件自带蒙特卡洛计算结果进行对比,结果表明该方法计算结果优于传统计算结果。Take a slop on the Yalong river area for example,used Monte Carlo sampling of the side slope rock soil physical mechanics parameter,compiled the cut-over program between the data sampling and the GEOSLOPE software.Calculate an assurance coefficient gradually in order to get the assurance coefficient mean value,variance,lose steady probability,and compare the results with the outcome by the GEOSLOPE software,the results of this method is superior to the results of calculation software.
