摘要
采用水平分层法在EXCEL中利用rand函数生成一系列的样本值,将每个样本值对应的强度参数输入有限差分程序中计算边坡的安全系数,统计安全系数小于1的样本数目与总体样本数目的比值,该比值即为边坡的失效概率,并通过算例分析验证了该方法的有效性。
The paper adopts the horizontal hierarchical method,forms a series of sample value with rand function in EXCEL,inputs the respective strength parameter of the sample value into to finite difference program,calculates the safety coefficient of the slope,sums up the ratio between the sample number and overall sample number whose safe coefficient is less than 1,and indicates the ratio is the failure probability of the slope,and proves the method is effective by the calculation example.
