大跨钢箱梁斜拉桥施工控制要点分析

由于大跨钢箱梁斜拉桥结构自身的特性，风载、温度荷载等对其施工控制影响较大，为确保此类桥施工控制的准确性，必须对施工控制计算参数进行识别，修正。本文以武汉军山长江大桥主桥大跨钢筋梁斜拉桥施工控制为实例，分析了影响大跨钢筋梁斜拉桥施工控制的这两大要点。

Analysis of Key-points for Construction Control of Long-span Steel Box-girder Cable-stayed Bridge

Construction control of long-sp an steel box-girder cable-stayed bridges will be influe nced dramatically by both wind and temperature load,owing to the struc tural characteristics. In order to control the construction of such br idges accurately, it′s necessary to verifying and adjusting calculating parameters to by control. Providing an instance of Wuhan Junshan Y angtze River Bridge, the thesis analyses the two key-p oints which influence construction control of long-span steel box-girder cable-stayed bridge.
