Abstract：Taking a subway station on Tianjin Metro Line 11 as a case study,the water resources demonstration and analysis for foundation pit dewatering were conducted.The project covers a total area of 12,230 m²,with the main station being an underground three-level island platform and a main foundation pit dewatering area of 3,938 m².The station includes two underground two-level air ducts and two entrances/exits,with an auxiliary foundation pit dewatering area of 2,480.5 m².Based on the collected design schemes for support,water-stopping,and dewatering wells,the dewatering volume of the foundation pit was calculated,and the impact of dewatering on the surrounding environment and water users was analyzed.
