本文利用概率的方法,在极限平衡法的基础上,考虑了节理、裂隙,岩体物理力学性质的随机性进行边坡稳定性分析.该方法考虑了计算参数的随机分布,使得计算结果更接近实际。本文较详细地介绍了破坏概率的计算,以及在设计边坡角时如何利用破坏概率。文章中给出了一个工程实例,说明如何利用破坏概率分析稳定性,本文较简单地论述了利用破坏概率来确定最优边坡角.
In this paper, based on the limit equilibrium method, the stochastic stability analysis of joints, fractures and physical and mechanical properties of rock mass is carried out based on the probabilistic method. This method takes into account the random distribution of the calculated parameters and makes the calculation results more similar actual. This paper introduces in more detail the calculation of the probability of failure and how to use the probability of failure in designing the slope angle. In this paper, an engineering example is given to illustrate how to analyze the stability by using the failure probability. In this paper, the probability of failure is used to determine the optimal slope angle.
