深圳市某工程基坑开挖前地质灾害分析

Geological Disasters Analysis before an Engineering Excavation of Foundation Pit

结合深圳市某建设工程实例,通过对不同工况下基坑边坡稳定性的计算,分析了该建设工程人工基坑开挖过程中面临的地质灾害类型,讨论了影响基坑边坡稳定性的几种因素,同时针对该工程基坑边坡地质灾害提出了有效防治措施.

Taking a construct ion project of Shenzhen as the example, this paper introduces the cl imate, hy-drology ,regional geology and human engineering activities of the engineering area, which analyzes the type of geo-logical disasters during the artificial excavation based on the calculation of foundation pit slope stability in differ-ent working conditions. Several factors affecting the stability of foundation pit slope are discussed, at the same time, several prevention measures for the foundation pit slope geological disaster of this project are put forward.
