三峡库区秭归县张家湾滑坡群基本特征及形成机制探讨

Basic features and genetic mechanism of Zhangjiawan landslide group in Zigui County of the Three Gorges reservoir area

在前人资料、勘探和工程地质测绘的基础上,通过对原始资料以及原斜坡地质环境的定性分析判断,指出张家湾滑坡是一个由6个单体滑坡组成的滑坡群体,阐述了各单体滑坡的基本特征、形成次序和相互关系,并对各单体滑坡的影响因素、形成机制和稳定性进行了评述。

According to former geological data and recent engineering exploration and mapping,qualitative analyses of geological environment of primary slopes show that the Zhangjiawan landslide is a landslide group composed of six landslides. The basic characteristics,controlling factors,genetic mechanism and stability of each landslide are discussed,and the forming order and their relationships are also evaluated.
