摘　　要：以工程实际为例，用MATLAB编制了公路边坡工程蒙特卡罗可靠度求解程序，通过计算结果分析表明模拟次数选择为3000次～5000次、土条数目划分为8条～10条较为合理，这时计算精度能够满足工程要求。In this paper, the corresponding software was drawn up by MATLAB for the calculation of reliability of highway slope engineering with Monte Carlo method taking the practice project. The calculate result shows that is quite reasonable when random simulation times is in the range of 3 000-5 000 times and the number d slices is variable with 8-10, and the accuracy of calculation on the slope stability analysis meet the engineering needs.
