抽取承压水引起地面沉降机理及危害OA
The Mechanism and Harm of the Land Subsidence Caused by the Extraction of Confined Water
地面沉降已经成为我国东部沿海城市的主要地质灾害，开采承压水是造成我国地面沉降的主要原因。本文以有效应力的原理，分析了抽取承压水造成地面沉降的机理，并对地面沉降造成的危害进行了阐述。
The ground subsidence has become the main geo- logical disaster in coastal city in the east of China. The exp- loitation of confined water is the main cause of Chinaʼs land subsidence. According to the principle of effective stress, the author analyzes the ground subsidence mechanism caused by extraction of confined water, and described the hazards caused by ground subsidence.
