滑(边)坡稳定性评估不仅取决于计算方法本身,更主要的取决于计算参数的选取是否合理,力学参数的选取是否合理将直接关系到所建立的滑(边)坡稳定性评估体系的成败。在根据试验结果等综合确定(潜在)滑动面的黏聚力、内摩擦角的取值区间和建立计算模型基础上,对滑(边)坡反算力学参数时不同发育条件下稳定系数的选取和稳定性计算方法的确定进行了较深入研究,提出了一整套滑(边)坡力学参数的综合选取方法和稳定性评估体系,并以某滑坡为例进行了实际工程应用。采用数值模拟和物理模拟对所建立的稳定性评估体系进行了验证,其工程适用性良好。
The evaluation of sliding (slope) slope stability depends not only on the calculation method itself, but also on whether the selection of calculation parameters is reasonable or not and whether the selection of mechanical parameters is reasonable or not is directly related to the stability of the established slope stability assessment system Success or failure. Based on the experimental results and other comprehensive determination of the potential cohesion of the sliding surface, the value of the internal friction angle interval and the establishment of the calculation model based on the slip (edge) slope back to calculate the mechanical parameters of different stability under the conditions of selection And stability calculation method, a set of comprehensive selection method and stability evaluation system of sliding (side) slope mechanical parameters are put forward. The practical engineering application of a landslide is taken as an example. The established stability evaluation system is verified by numerical simulation and physical simulation, and its engineering applicability is good.
