摘要
利用蒙特—卡洛法模拟岩土力学参数的随机分布评价大型山区滑坡危险性,讨论了岩土参数的离散型和随机分布特点对滑坡概率的影响。通过在中国西南山区某大型特高压线路工程选线过程中实践,得到了该工程区域内滑坡概率分布情况。
This paper had presented the study of landslide hazard assessment of large mountain area by using the Montel-Carlo method to simulate the random distribution of geo-mechanical parameters and the probability of failure had been discussed with the change of parameters and distribution. With the example of High voltage transmission line project in southwest mountain area of china, we had gotten the distribution of probability of failure with this method.
