岩溶地区地面塌陷的发生规律及治理

Rules and Remedies of Surface Subsidece in Karst Area

对地面塌陷的形态特征 ,分布规律、形成机理做了探讨。地面塌陷的天然条件取决于岩溶发育程度、富水性的强弱 ,并受水位降低幅度、第四纪覆盖层厚度及岩性、地表水与地下水的水力联系。同时介绍了治理措施等。

This paper explores the features,distribution regularity,formation mechanism of surface subsidence and its remedial methods based on the analysis of the railway construction and the mine pit driving in south China.It points out that is mainly caused by drastic lowering groundwater level or excessive pumping of groundwater.Therefore soil caves are formed and the subsidence are developed.This paper also presents some of geophysics exploration which can determine karst growth zone and some comprehensive remedial measures.
