果子沟特大桥上部结构设计与施工

Design and Construction of Supperstructure of Guozigou Long Span Bridge

果子沟特大桥上部结构采用钢桁梁,钢桁梁主要分主桁和桥面系两个部分。本桥交通运输条件极为困难,且施工场地狭窄,钢桁梁构件可小型化、工厂化,易于运输和吊装。主要结合钢桁梁的设计和施工方案做相关阐述,为类似桥梁建设提供借鉴和参考。

The steel truss girders are adopted in the supperstructure of Guozigou Bridge and there are mainly two parts—main truss and bridge deck.The transportation condition on this bridge is extremely difficult,and the construction site is narrow.The stell truss girders component can be miniaturized and factory-produced to be easily transported and installed.The design and construction scheme of the steel truss girders are mainly discussed to offer the reference for the similar bridge construction.
