【 摘 要 】

Even a slight subsidence of metro may lead to a severe threat to the safety of metro operation. Groundwater recharge is a valid manner to control the subsidence caused by dewatering. The recharge application in the foundation pit near Metro Line 8 in Shanghai shows that the recharge can effectively rise the water level and even rebound the ground, which ensures the safety of deep foundation pit excavation. The result can help the design of recharge well for projects with similar hydrogeological conditions.
