摘要
滑带抗剪强度参数(C、φ值)是影响滑坡体稳定性的主要因素,本文以某滑坡为例,根据岩土物理力学性质指标的试验结果以及滑坡稳定性反演分析结果,采用传递系数法,分不同的工况条件进行滑坡稳定性计算。以C、φ值作敏感性分析,研究其对滑坡稳定性的影响,为下步防治提供依据。
The shear strength parameters(C and φ value) of slip band are important factors for the stability of landslide. This paper takes a landslide as an example and calculates the landslide stabilities under different working conditions by using the transfer coefifcient method bases on the experiment results of physical and mechanical properties of rock-soils and the inverse analysis results of the stability of landslide. It analyzes the sensibility of the C and φ value and studies their inlfuences and functions to the landslide stability.,and provides a basis for prevention and treatment in the next stage.
