富水软弱地层地铁车站结构防水设计与渗漏水控制措施

Waterproof Design and Leakage Control Measures of Subway Station Structure in Water-Rich Soft Stratum

摘要: 富水软弱地层地下水渗流对在建地铁车站的施工安全与后期运营都存在重大危害。为此，依托深圳地铁7号线上沙车站结构防水工程，详细阐述了该车站结构防水设计原则与方法，揭示了结构缝隙渗漏水危害机理，提出了有效的控制措施，为富水软弱地层车站结构防水设计提供了重要参考。

Abstract: The seepage of groundwater in the weak water-bearing strata has great harm to the construction safety and post-operation of the subway station. To this end, relying on the Shenzhen Metro Line 7 on the sand station structural waterproofing works, the principle and method of waterproof design of the station structure are expounded in detail to reveal the structural gap leakage water hazard mechanism. And put forward the effective control measures, which provides an important reference for the waterproof design of the water.
