| Abstract: | 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 construction in the design of the bridge and results of the implementation of the closing are dealt with. |
