摘要
滑坡水文地质特征是滑坡防治必须查明的重要地质问题。针对如何分析、研究滑坡水文地质特征,选择利用勘探钻孔、竖井进行滑坡透水性测试与地下水位观测,尤其是滑坡体地下水位分层观测等综合手段与方法的应用,证实长江三峡库区万州和平广场滑坡不同地质单元之间存在水力联系。滑坡稳定性分析应根据滑坡不同水文地质特征,分别考虑地下水压力的影响。
Hydrogeological featuer of a landslide is an important geological problem and must be investigated clearly in preventing landslides. For the sake of how to analyze and study the hydrogeological feature of a landslide, the permeability of the rock and soil of the landslide must be tested and the groundwater head observed by using exploration hole and vertical shaft, especially the method of layered observation. Different geological units and their connection were found out for the Heping Square landslide of Wanzhou in the Three Gorges of Yangtze River. According to the different hydrogeologic features of the landslide, the (influences) of different pressures of groundwater should be considered in analyzing the landslide stability.
