摘要
降雨与水位涨落是诱发滑坡的重要因素.本文收集八字门滑坡监测资料和三峡库区库水位、降雨等资料.运用定性分析方法分析出八字门滑坡的形成机理,得出八字门滑坡累积位移监测曲线阶梯形状并随着时间呈增长趋势,其中监测点ZG110、ZG111的位移具有同步性;并分析出八字门滑坡变形演化有3个很重要阶段.最后利用定性比较分析法,得出每个阶段累积位移变化特征.
Rainfall and fluctuation of water level are important factors to induce landslides. In this paper, the monitoring data of the landslide and the data of the water level and rainfall in the reservoir area of the Three Gorges Reservoir area are collected. First of all, we use qualitative analysis to analyze the formation mecha nism of the Bazimen Landslide. We can get the ladder shape of the cumulative displacement monitoring curve of the Bazimen Landslide and increase with time. The displacements of monitoring points ZG110 and ZGI 11 are synchronous, and the deformation evolution of the Bazimen Landslide has three important stages. Finally, the characteristics of cumulative displacement in each stage are obtained by qualitative comparison analysis.
