桥梁改造工程中同步顶升技术应用及控制重点

An application of synchronous lifting technology and control points in the bridge reconstruction project

结合京九铁路电气化改造工程建设中对既有铁路跨线桥进行整体顶升实例,介绍了同步顶升技术在桥梁顶升工程中的具体应用及顶升过程中的一些关键问题,说明了桥梁整体顶升技术可以应用于既有线改造,对同类工程中应用此项技术时有较高的参考价值。

Integrating with the overall lifting instance on the existing railway of Beijing-Kowloon railway electrification project,it introduces the application of the synchronous lifting technology in bridge jacking and some of the key issues in the process of lifting.It shows that entire bridge lifting techniques can be applied to transform the existing lines,which has a higher reference value to the application of this technology in the similar projects.
