摘要
重庆石板坡长江大桥复线桥主跨(330 m)的103 m钢箱梁段为整体吊装合龙,在温度变化下的大尺寸合龙是技术难度较高的工作。介绍在桥梁设计中对合龙的考虑和实施结果。
The 103 m long portion steel box girder structure for the main span （330 m in length） of the double-line bridge of Shibanpo Changjiang River Bridge in Chongqing is erected and closed by heavy lifting method. The closing of such huge size structure under condition of varying temperatures is indeed a technical challenge. In this paper, the considerations for the closing con struetion in the design of the bridge and results of the implementation of the closing are dealt with.
