摘要
Abstract
In order to verify the water-proof capacity of the envelope structure,and predict the impact of dewatering con-struction on the surrounding environment.Through the dewatering test performed before the excavation of a foundation pit in a station of Tianjin Metro,the paper clarifies the main reason for the lowered water levels of the phreatic aquifer and the first confined aquifer,analyzes the horizontal displacement of the diaphragm wall,ground subsidence and subsidence of nearby buildings in the excavation of the station.It is considered that improving the construction quality of the diaphragm wall and avoiding excessive dewatering depth at one time can effectively control the influence of dewatering on the surrounding environment.关键词
