文章以缅甸道耶坎引水洞进口左侧滑坡为研究对象,在前人研究成果和现场详细地质勘测的基础上,全面分析了滑坡发生的地质环境背景。通过对滑坡体的地形地貌特征、物质组成特征、变形破坏特征的研究,分析了滑坡的形成机理。利用极限平衡法对滑坡体的整体稳定性进行了分析和评价,并通过离散元数值分析法对滑坡体进行仿真模拟,对滑坡体内的应力、应变及塑性区分布特征有一个全面的了解和认识,同时提出了相应的滑坡治理方案。
The article takes the left landslide of the Doyeikan diversion tunnel in Myanmar as the research object. Based on the previous research results and the detailed geologic survey on the site, the paper comprehensively analyzes the geo-environmental background of the landslide. Through the study of landslide features, material composition features and deformation and failure characteristics of landslide bodies, the formation mechanism of landslides is analyzed. The limit equilibrium method is used to analyze and evaluate the overall stability of the landslide body. The landslide body is simulated and simulated by discrete element numerical analysis. The stress, strain and plastic zone distribution characteristics in the landslide body have a comprehensive understanding and understanding , At the same time put forward the corresponding landslide control plan.
