苏通大桥268m跨径连续刚构桥施工线形控制

Construction Alignment Monitoring of 268m Continuous Rigid Frame Bridge of Sutong Bridge

从施工线形控制的总体思路和方法、线形控制计算、施工阶段线形控制方法、主梁线形纠正等方面阐述了苏通大桥268m跨径连续刚构桥的施工线形控制方法,并以实测数据证明了该方法的合理性。

This paper introduces construction alignment monitoring method of 268 m continuous rigid frame bridge of Sutong bridge from aspects of general control idea and method,alignment control computation,alignment control methods during different construction stages,alignment correction of main girder,et al.It is proved that the control methods are rationality by measured data.
