摘要
Abstract
The design of water inflow in a foundation pit,the number and layout of dewatering wells around the foundation pit were analyzed and studied by referring to the construction characteristics of the foundation pit of water-intake pump shed in a LNG terminal project,including the impact of the foundation pit dewatering on the surrounding environment,the feasibility and necessity of dewatering&decompression design and environmental impact analysis of littoral deep foundation pit projects.To verify the effectiveness of dewatering before construction could avoid groundwater surging and water leakage of retaining walls during the excavation of foundation pit,and ensure a dry working condition.The influence on the surrounding buildings by the foundation pit excavation was analyzed,which served as a theoretical guide for the excavation of foundation pit.关键词
