Application research of composite material evacuation platform in coastal elevated sections

为验证复合材料疏散平台应用于沿海地铁高架段的可行性,本研究分析了沿海地铁高架段的各种极端工况,再利用仿真计算和加速老化试验合理评价了高分子复合材料疏散平台的各项指标,最后对比了复合材料疏散平台与高架段常用的活性粉末混凝土疏散平台的综合性能。研究结果表明:现有复合材料疏散平台能够满足沿海地铁高架段存在的大风、长期暴晒、盐雾腐蚀等特殊工况,并且复合材料疏散平台在重量、强度、施工便捷性方面均优于活性粉末混凝土疏散平台。

To verify the feasibility of applying composite material evacuation platforms to coastal subway elevated sections,this study analyzed various extreme working conditions of coastal subway elevated sections,and then used simulation calculations and accelerated aging tests to reasonably evaluate the various indicators of polymer composite material evacuation platforms.Finally,the comprehensive performance of composite material evacuation platforms and commonly used active powder concrete evacuation platforms in elevated sections was compared.The research results indicate that the existing composite material evacuation platform can meet the special working conditions of strong winds,long-term exposure to sunlight,salt spray corrosion,etc.in the elevated sections of coastal subways,and the composite material evacuation platform is superior to the active powder concrete evacuation platform in terms of weight,strength,and construction convenience.
