摘要
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。
An updated Lagrangian finite element formulation has been developed for analyzing
the stabiligy of Shilongmiao landslide which involves large deformation, initial stress and
excess pore water pressure. According to the engineering geological properties of the soil, the
landslide body is divided into 4 layers. The soil layers are considered to be elasto plastic
material and the Drucker Prager yield criterion for ideal plasticity is used. The stress and
deformation of the landslide are analyzed and discussed before and after the retaining wall is
built. Finally, in the light of these analysis results, the treating project landslide is proposed
and carried out.
