摘　　要：目前地铁疏散平台材料主要有预制钢筋混凝土、SP预应力空心板、钢材、树脂基复合材料、水泥基、活性粉末混凝土。由于各种材料均有其优缺点,确定合适的疏散平台材料一直困扰着参建各方。通过疏散平台材料特性对比分析,以及疏散平台现状应用的分析,经综合比选,推荐采用RPC材料作为疏散平台选型材料。At present,the main materials of subway evacuation platform are prefabricated reinforced concrete,SP prestressing hollow slab,steel,resin-based composite material,cement-based concrete and reactive powder concrete.Due to the advantages and disadvantages of different kinds of materials,it has been a long-term headache for all parties involved in the construction to determine the appropriate evacuation platform materials.Through comparative analysis of material characteristics of evacuation platform and application analysis of the current situation of evacuation platform,RPC material is recommended as the chosen material for evacuation platform after comprehensive comparison and selection.
