滑坡滑带土抗剪强度参数的合理选取是进行滑坡稳定性分析和治理设计的关键。本文结合滑坡的发育阶段,合理选取滑坡稳定性评价指标,基于反分析的基本原理,利用至少两个反分析剖面,采用试算、插值和图解法求解滑带土的抗剪强度参数,对比室内剪切试验数据,该方法最终所得参数基本满足工程要求,可为其它滑坡的稳定性分析及治理工程设计提供借鉴。
The reasonable selection of shear strength parameters of landslide is the key to landslide stability analysis and treatment design. Based on the basic principle of back analysis, this paper, based on the development stage of landslide, reasonably selects the evaluation indexes of landslide stability. Based on the basic principle of back analysis, the shear strength parameters of landslide soil are calculated by using trial calculation, interpolation and graphic method, Shear test data, the final parameters obtained by the method basically meet the engineering requirements, which can provide reference for other landslide stability analysis and treatment engineering design.
