摘要
位于长江北岸的周家湾滑坡是著名的黄蜡石古滑坡群的重要组成部分,其变形始于20世纪80年代中期,地面开始出现张拉裂缝,近几年来变形逐步加剧,目前该滑坡处于蠕滑阶段。周家湾滑坡前缘为石榴树包滑坡的后壁,因此,周家湾滑坡对石榴树包滑坡存在潜在的威胁。文章在分析了周家湾滑坡体的地质环境、形态、结构等空间要素的基础上,运用工程地质力学分析原理重点剖析了其形成演化机制,可供滑坡治理工程设计时参考。
Zhoujiawan landslide which is located on the north bank of the Yangzi River is an important part of the well-known Huanglashi landslide group in Three Gorges reservoir area. The obvious deformation of the landslide began in the middle age of the 1980s, when many cracks occurred on grounds. In recent years, the deformation of the landslide is pricking up, and it is on the creep stage. The existence of Zhoujiawan landslide is a potential threat because there is a Shiliushubao landslide in the front of Zhoujiawan landslide. In this paper, the stress is lald on research of the developing mechanism of the landslide based on the analysis of the key spatial factors such as the geologic environment, pattern and structures, etc. by means of engineering geology and mechanics. The paper can be served as a reference for landslide control engineering design.
