| 摘 要： | Rosenblueth方法是一种简单实用的可靠度指标计算方法，不需要了解各状态变量分布函数，只要利用它们的均值和方差，就可求得边坡的可靠指标。推导了下滑力超载储备安全系数的显式表达式，以此式作为边坡可靠度分析的状态函数，结合Rosenblueth方法的优点，给出了一种边坡稳定可靠度分析的实用方法。

| Abstract: | The Rosenblueth Method is a simple and practical calculation method of reliability index as the probabi- lity distribution of all kinds of state variables does not need to be known, and only by using the averages and variances of state variables can one get the reliability index of soil slope. In this paper an explicit expression about landslide load-increased factor is deduced. Using the expression as the status function of reliability analysis and the advantage of Rosenblueth Method, a method of calculating the reliability of slope is put forward. |
