摘　　要：既有铁路框构桥顶进施工,选取一种既能减少对铁路运行的影响又能保证顶进作业安全、又能降低施工成本且方便施工组织的线路加固方法,是顶进施工的关键技术环节。本文针对横向结构跨度大、线路多、架空加固难度大等问题,介绍一套线路加固方法。In the jacking construction of existing railway frame bridges, it is the key technical link of jacking construction to select a line reinforcement method which can not only reduce the impact on Railway operation, but also ensure the safety of jacking operation, reduce construction cost and facilitate construction organization. In this paper, aiming at the problems of large span of transverse structure, many lines and difficulty of overhead reinforcement, a set of methods of line reinforcement is introduced.
