摘　　要：目前,明挖地铁车站结构设计有叠合衬砌和复合衬砌两种形式,因此,外包防水层的设置也不尽相同。随着混凝土结构耐久性设计理念的深入,本文综合了上述两种结构形式的优点,分析和探索了一种新型的地铁车站结构及防水形式,以适应腐蚀性环境下的结构耐久性设计要求。At present, for the underground subway station built by cut and cover method, the internal wall either bears the forces independently or bears the forces together with the retaining wall. Then, the waterproofing design is also different for the two conditions. With the deep understanding of the philosophy of concrete durability design, taking the advantages of the above two structural styles in consideration, a new structural style and its waterproofing design are proposed, which could adapt to the structural durability requirements in corrosive environment.
