摘　　要：地铁工程大多位于地下,易出现渗漏水问题,做好地铁工程防水验收工作尤为重要。文章提出微水压环境的混凝土结构实体防渗漏质量检测技术,该技术在结构内部通过真空泵和吸盘,为地下建筑主体混凝土背水面结构表面提供负压,检测结构是否具有抵御设计高水位压力下的抗渗漏能力。相关研究可为地铁工程结构防渗漏水质量检测提供参考和借鉴。Most metro projects are located underground,which is prone to water seepage,so it is particularly important to excel in the waterproof acceptance of metro projects.This paper puts forward the anti-seepage quality testing technology of concrete structure entities in micro-artesian environment.This technology provides suction for the surface of the concrete back surface of the main body of the underground building through the vacuum pump and suction cup inside the structure,and detects whether the structure has anti leakage ability against the designed high water level pressure.The relevant research can provide reference for the anti-seepage quality testing of metro structures.
