本文应用UpdatedLagrangian有限元分析理论,分析了石龙庙滑坡的稳定性,其中包括滑坡的大变形、初始应力和超孔隙水压力。根据土的工程地质性质,滑坡体分为四层。土层被视为是弹塑性的,土的塑性屈服采用Drucker-Prager理想塑性屈服准则。挡土墙建成前后的滑坡应力和变形被分别分析和讨论,最后根据这些分析结果,提出了滑坡的整治方案。
In this paper, we use the UpdatedLagrangian finite element analysis theory to analyze the stability of Shilongmiao landslide, including the large deformation, initial stress and excess pore pressure of landslides. According to the engineering geological nature of the soil, landslide body is divided into four layers. The soil is considered elastoplastic, and the plastic ductile yield of soil follows the Drucker-Prager ideal plastic yield criterion. The landslide stress and deformation before and after the construction of the retaining wall are separately analyzed and discussed. Finally, based on these analysis results, the landslide remediation plan is put forward.
