不稳定概率法分析边坡的稳定性研究

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,因此对于模型问题采用精确的数值来表达是不合理的,概率分析方法则克服了这一缺憾。与传统的基于极限平衡理论的定数论方法相比,不稳定概率法在设计边坡时考虑了摩擦系数、粘聚力、重度等参数的变异性,能更好地反映滑坡所处的状态,是一种崭新的滑坡评价方法。

Study on Analysis of the Probability of Slope Instability in the Stability

The traditional mathematical-mechanical model is applied to calculating the safety factor of landslipe by certain parameters.But people cannot know the geologic body enough due to its complexity.So,it is improper to solve the fuzzy problem by the accurate numerical value.The probability analysis method is more advanced the traditional way in this aspect with the traditional limit equilibrium theory methods.The parameters severe changes of the friction coefficient,cohesion be taked into account in the slope ...
