摘要: 林达滑坡的稳定性问题对其上游林达电站、下游乐安电站、乐安乡及尼古寺的安全至关重要。本文利用GeoStudio软件根据滑坡体地质模型，构建典型剖面的渗流分析模型，采用有限元GeoStudio渗流分析模块SEEP模拟渗流。运用SLOPE模块对林达滑坡进行稳定性刚体极限平衡分析。分析研究表名：天然工况下，林达滑坡主滑体内1#次级滑体处于稳定状态；暴雨工况下，主滑体内1#次级滑体处于基本稳定–稳定状态。本文的研究为今后林达滑坡的稳定性安全设计和评价提供了一定的参考依据。
Abstract: The stability of the Linda landslide is of great importance to the safety of the upstream Linda power station, the downstream Le’an power station, Le’an township and Nigu temple. In this paper, GeoStudio software is used to build the seepage analysis model of typical section according to the geological model of landslide body, and the finite element GeoStudio seepage analysis module SEEP is used to simulate seepage. The SLOPE module is used to analyze the rigid limit equilibrium of the Linda landslide stability. Table name of analysis and research: under natural working condition, No. 1 secondary sliding body in main sliding body of Linda landslide is in stable state; under the rainstorm condition, the #1 secondary sliding body in the main sliding body is in the basic stable-stable state. The research in this paper has provided a certain reference basis for the sta-bility and safety design and evaluation of Linda landslide in the future.
