摘　　要：以长沙市福元路湘江大桥河东水中引桥为工程背景,从理论无应力线形的确定、制造构形的设置、拼装线形的控制等三个方面对钢槽梁线形控制进行了论述,以期为同类桥梁提供参考。Taking the east approach of Changsha Fuyuan bridge over Xiangjiang river as the engineering background, geometry control of the steel channel girder, including the definition of the theoretically unstressed geometry, the set of fabrication configuration and the control of the assembly geometry is studied to provide the reference for the similar bridges.

关 键 词：顶推法 无应力线形 制造构形 拼装线形
