传统的数学-力学模型是通过确定的参数来进行滑坡体的稳定性评价,由于人们对地质体属性的了解是随机的、不全面的,因此对于模糊问题采用精确的数值来表达是不合适的,概率分析法则克服了这一缺憾。笔者应用概率分析法分析了岩村滑坡在3种工况下的破坏概率,并将其结果与剩余推力法的结果进行对比,结果表明两种方法得出的结论基本一致,并且概率分析法能更好地反映滑坡所处的状态。
The traditional mathematic-mechanical model evaluates the stability of the landslide body through certain parameters. Because people’s understanding of geological body properties is random and incomplete, it is not suitable to express the value of the fuzzy problem with exact values Probability analysis rules overcome this shortcoming. Probability analysis method is used to analyze the failure probability of rock landslides in three conditions, and the results are compared with the results of the remaining thrust method. The results show that the two methods are basically the same, and the probability analysis method can be more Well reflect the state of the landslide.
