滑坡动态变形过程的综合研究方法

影响滑坡变形破坏过程的因素具有复杂性和多变性，要合理评价和预测滑坡的动态发展过程，深入的地质原型调查是基础，地质分析不仅能为其它分析方法的正确使用提供资料，而且能直接对滑坡的变形破坏发展过程作出定性的判断。在此基础上建立力学模型，采用数学力学理论进行定量计算和反演分析，可进一步从本质上去把握滑坡变形破坏的发展规律。本文通过介绍李家峡水电站Ⅱ号滑坡的研究实践，说明了采用定性地质分析与定量力学计算相结合的研究方法揭示滑坡变形破坏动态过程的有效性。

Synthetic study method of dynamic deformation process of landslide

The influence factors of a landslide deformation are complex and changeful. Therefore, ge- ological investigation is very important for evaluating and forecasting the dynamic deformation pro- cess of a landslide. Geological investigations can not only obtain basic data for mechanical calculation but also make a qualitative forecast. Based on geological analyses, it is necessary to es- tablish a mechanical model for quantitative calculation and inverse analysis. The deformation mecha- nism will be discovered by quantitative mechanical analyses. In dynamic deformation process analy- sis, it is effcient to combine qualitative geological analysis with quantitative mechanical calculation. As an example, a study result of the number 2 landslide at Lijiaxia Hydropower Station is intro-duced in this paper.
