针对现正施工使用的地铁结构施工缝防水进行详细描述及比较，并从施工层面及结果层面分析了各种施工缝防水处理方法的利弊。具体介绍了施工缝的三种处理方法：双道遇水膨胀嵌缝胶与注浆管配合防水、钢边橡胶止水带、缓膨胀型膨润土橡胶遇水膨胀止水条，及三种处理方法的材料材质的性能、安装方法和防水原理，以及三种方法的适用范围。

The construction joint Waterproofing methods of Metro works that are at present in use are described and compared in detail. The advantages and disadvantages of the Waterproofing methods are analyzed in terms of Waterproofing construction and Waterproofing effect. Three construction joint Waterproofing methods, i.e., Waterproofing by means of double expandable caulking glues and grouting pipes, Waterproofing by means of steeledged rubber water stripes and Waterproofing by means of prefabricated expandable rubber water stops, are presented. The material performances, installation methods, Waterproofing principles and application scopes of the mentioned three Waterproofing methods are described in the paper.
