摘　　要：对隧道保护范围内的防汛墙进行耐久性加固,可避免因防汛墙大修而给隧道带来的不利影响,保障隧道和防汛墙安全。以上海轨道交通14号线穿越黄浦江段防汛墙的耐久性加固工程为案例,分析了防汛墙耐久性影响因素,介绍了在防汛墙外立面采用“双层聚合物水泥防水砂浆+硅烷浸渍剂”加固方案的设计和施工过程,并通过结构复核和耐久性评定验证了该加固方案的合理性。研究思路可为类似堤防维修加固工程提供参考和借鉴。The durability reinforcement of flood control walls within the scope of tunnel protection can avoid the adverse impact on the tunnel caused by the overhaul of the flood control wall in order to ensure the safety of tunnel and flood control wall.Taking the durability reinforcement of flood control wall in Huangpu River Section above Shanghai Metro Line 14 as a case,the factors affecting the durability of flood control wall are analyzed,and the design and construction process of"double-layer polymer cement waterproof mortar+silane impregnant"reinforcement scheme on the exterior facade of flood control wall is introduced.And the rationality of the reinforcement scheme is verified through the structural review and durability evaluation.The study idea can provide reference for similar embankment maintenance and reinforcement projects.
