| Abstract: | The paper introduced the groundwater level control by continuous small pumping amount in multiple well points for the foundation pit construction with full water recharge and large drawdown,which made the curved surface of dewatering funnel flat,reduced the land subsidence around the foundation pit and obtained good dewatering result. |
