摘要
Rosenblueth方法是一种简单实用的可靠度指标计算方法 ,不需要了解各种状态变量的概率分布 ,只要利用它们的均值和方差 ,就可以求得边坡的可靠度指标 ,其计算满足精度要求。Rosenblueth方法计算所需的数据较少 ,利于计算机处理。论述了Rosenblueth方法的基本原理 ,用FORTRAN语言编制了计算程序 ,并通过算例比较证明了Rosenblueth方法的优点。在工程实际分析运用中 ,是一种值得推广应用的方法。
As a simple and new calculation method of reliability index,Rosenblu eth method dosen’t need to know the probability distribution of all kinds of st ate variable.Only by the averages and variance of state variable we can get the reliability index of soil slopes,and the calculate accuracy meet precision deman ds.Rosenblueth method dosen’t need to calculate much data and is easily handed by computer.The fundamental principle of Rosenblueth method have been presented in detail. We use the FORTRAN language to write the calculator program and prove its advantage by comparison.It’s a method that is worthy of applicating in the engineering practice.
