Stability analysis and remediation effect study of Taohuafeng landslide
This study focuses on the stability analysis and remediation effect of the Taohuafeng landslide. By analyzing the basic characteristics of the landslide,the factors influencing its stability are identified. The residual thrust method is employed to calculate the stability coefficients of three representative profiles of the landslide. Based on the stability analysis,a remediation plan involving slope reduction,grid beam anchoring,and construction of drainage ditches is proposed. Three-dimensional mesh models and groundwater level models are established to simulate the displacement distribution of the landslide under natural conditions( without considering groundwater levels)and heavy rainfall conditions( considering groundwater levels)using the finite difference method. The effectiveness of the proposed remediation plan is validated,and it is revealed through comparative analysis that groundwater levels have a significant impact on the stability of the landslide,resulting in soil displacement in the deep part of the landslide. This research provides valuable references for similar landslide stability analysis,remediation plan design,and verification.
