铁路新型80m钢-混凝土组合桁梁桥施工技术研究

New railway 80-m steel and concrete composite truss construction technology

钢-混凝土组合桁架梁桥是一种新型的桥梁结构形式,它能充分发挥不同材料的优点,具有重量轻和跨越能力强等特点。西平铁路后河村80m钢-混凝土组合桁梁桥是目前世界上此类结构跨度最大的铁路桥,技术含量较高,施工难度大,对该桥梁施工技术的研究将为同类型桥梁设计与建设提供参考。

Steel concrete composite truss bridge is a new type of bridge structure, which can give full play to the advantages of different materials, such as light weight, strong ability to cross and so on. Xiping railway, river village of 80m steel - concrete composite truss girder bridge is currently the world on such kind of structure span the largest railway bridge, is also the first seat adopts the structure of the bridge, high technology content and difficulty in construction, research on the construction technology of the bridge will at the same time provide reference for the type of bridge design and construction.
