Research on Stability Analysis and Prevention Design of Landslides
In response to the uncertainty of soil strength parameters,this paper proposes a theoretical and numerical landslide stability analysis method and countermeasures.The reliability method results and quantitative method are combined with in-situ geological tests to comprehen-sively determine the reasonable values of soil strength parameters.In order to evaluate slope stability,the upper limit method and strength re-duction method were used for limit analysis and finite element simulation,respectively.Taking the study of a certain landslide as an example,it was shown that stress and strain are mainly concentrated at the toe and top of the slope.Based on the analysis results,strategies such as lat-tice anchor rod retaining walls,landslide piles,and crack filling were proposed to reduce the risk of landslide failure;Finally,the feasibility and effectiveness of the proposed approach were verified based on the results of finite element analysis.
