摘　　要：结合跨越既有线的自锚式拱桥的施工过程,对施工支架、对拉系统、转体施工过程及转体前后的动力特性进行了分析,并结合设计值进行施工过程控制。监控结果表明,施工过程控制符合设计要求,施工过程平稳,工程施工得以顺利进行。Combined with the plane rotation construction process of long span self-anchored arch bridge in the super-speed railway line which was across existing railway, it analysed the construction support, opposed pulling system, and the dynamic characteristics during and after rotation construction, and with the design value to control the construction process. Monitoring results showed that the construction process control meets the design requirements, the construction process is stable, the construction progress smoothly.
