摘　　要：地下混凝土结构常采用防水混凝土或附加防水层的防水做法,但结构设计时根据平面形状、荷载、地质变化等需要设置变形缝、诱导缝和后浇带,施工过程中也根据需要设置施工缝,这些薄弱部位以及防水层施工不到位都是混凝土成型后产生渗漏的主要原因。论文对地下结构工程防水质量通病进行分析,提出加强防水施工的质量控制措施,并就防水卷材搭接施工提出一种注浆封口施工工艺,为增强防水卷材连接质量提供了可靠的技术路径。The waterproofing method of the underground concrete structure facing the water is usually to use waterproof concrete or a waterproof concrete structure with a waterproof layer.However,when designing the structure,it is necessary to set deformation joints,induction joints and post-poured strip according to the plane shape,load,and geological changes.These weak parts and the insufficient construction of the waterproof layer are the main reasons for leakage after the concrete is formed.This paper analyzes the common problems of waterproof quality in underground structure engineering,proposes quality control measures to strengthen waterproof construction,and proposes a pressure grouting sealing waterproof membrane construction process for the waterproof membrane overlap construction.
