摘要
衢宁铁路(福建段)地州大桥位于地州车站(列车会让站),同时又位于25.528km隧道群紧急救援站内。桥台均与隧道相连,桥址地形险峻,施工安全风险高,运输组织难度大,实现工期目标困难。以地州大桥站台梁及救援通道施工为依托,对钢管柱+贝雷梁支架在艰险地形站台梁及救援通道施工中的应用进行探究,主要从大型钢栈桥应用、支架设计及施工方面进行分析总结,其成功经验望能为以后类似工程施工起到一定的参考和借鉴作用。
Dizhou Bridge of Quning Railway(Fujian Section)is located in Dizhou Station(train concession station)and emergency rescue station of 25.528 km tunnel group.The abutments are all connected with tunnels.The terrain of the bridge site is steep,the construction safety risk is high,the transportation organization is difficult,and it is difficult to achieve the target of the construction period.Based on the construction of platform beam and rescue passage of Dizhou Bridge,this paper explores the application of steel pipe column and Bailey beam bracket in the construction of platform beam and rescue passage in difficult terrain.It mainly analyses and summarizes the application of large steel trestle bridge,bracket design and construction,and its successful experience is expected to provide a reference for the construction of similar projects in the future.
