摘　　要：某铁路客站改扩建工程,有2条铁路股道为货运列车专用通道,列车通行频繁,并且列车完全不能停运。在繁忙的铁路股道干线上空建设1座高铁车站的候车厅,如何建设混凝土结构候车厅楼板是关键所在,如何避免模板支撑体系搭设和楼板建设过程中对铁路列车通行产生影响是工程建设的重点和难点。通过方案比选,采用钢支撑平台转换的模板支撑方案。钢支撑平台作为楼板和满堂脚手架模板支撑转换传力结构,保障了下方列车通行不受工程建设影响,可最大程度提高和保证候车厅楼板结构建设的工效和安全性。In some reconstruction and expansion project of a railway station, there are two railway tracks are dedicated for freight trains, where trains pass frequently, and the trains can’t be stopped. In order to build a waiting hall of a high-speed railway station over the busy railway trunk line, the concrete waiting hall floor building is the key. How to avoid the impact of formwork support system and floor construction on the railway is the key and difficult point of engineering construction. By using the method of steel support platform conversion, the above problems can be effectively solved. The steel support platform is used as the force transforming structure of the floor and its full scaffold formwork support after scheme comparison. The steel support platform can protect the train traffic below from the impact of engineering construction, and can maximize and ensure the efficiency and safety of the waiting hall floor structure construction.
