摘要
以四川马崩组渔湾组滑坡为例,论文介绍滑坡的基本特征、H2滑坡现状变形特征、H2滑坡物质组成,通过室内试验、反演分析、工程类比并参考地区经验,确定H2滑带土抗剪强度指标推荐值,建立数值模型进行不同工况下的滑坡稳定性分析,计算结果与现状变形特征较为吻合。
Taking the landslide of Yuwan Formation and Mabeng Formation in Sichuan as an example,the paper introduces the basic characteristics of landslide,current deformation characteristics and landslide material composition of H2 landslide.The recommended value of shear strength index of H2 slip zone soil was determined by laboratory test,inverse analysis,engineering analogy and reference to regional experience,the numerical model is established to analyze the landslide stability under different working conditions,and the calculated results are in good agreement with the current deformation characteristics.
