摘　　要：速凝橡胶沥青材料与高分子自粘胶膜复合防水体系是一种新的地铁防水体系,该体系对喷射混凝土基层的开裂与变形有较好的适应能力,当复合防水体系损坏后具有自愈能力,可为地铁工程的耐久性提供保障。该体系用于北京地铁某车站工程中,使防水体系与混凝土结构形成了高效的"皮肤式"粘结效果。The composite waterproofing system of quick-setting rubber asphalt material and polymer self-adhesive film is a kind of new metro waterproofing system.The system has good adaptability to cracking and deformation of the sprayed concrete base layer.When the composite waterproofing system is damaged,it has self-healing ability,which can provide guarantee for durability of metro projects.The system is used in a Beijing metro station project to form an efficient"skin-like"bonding effect between the waterproof system and the concrete structure.
