为了深入研究近坝库岸滑坡的形成机理,首先分析了区域地下水的溶蚀作用和动水压力作用,又运用综合评分法确定出了对滑坡形成有利的优势结构面,发现区域滑坡滑带的形成是地下水与优势结构面长期联合作用的结果. 以龙羊峡滑坡为例,揭示了半成岩湖相地层中滑坡滑带独特的三段式结构特征,验证了地下水与优势结构面的联合效应对近坝库岸滑坡形成的控制作用

Other Abstract

In order to further research the mechanism of landslide near the Longyangxia dam, first we analyze the dissolution and dynamic hydraulic pressure of groundwater in this region. Then the comprehensive pointrating method is used to determinate the preferred planes beneficial to the landslides. It is found that the formation of sliding surface of landslide is the result of long-term joint action of groundwater and preferred structural plane. Taking Longyang landslide as an example, the special three-segment structures of landslide-slip zone in hypabyssal rock of lacustrine deposits are revealed. It is proved that the joint action of groundwater and preferred structural plane dominates the formation of landslide near the reservoir dam
