通常情况下,在进行铁路桥涵顶进施工的过程中,为保障铁路线路的稳定运行,往往需要对既有铁路线路进行必要的加固处理。在对既有铁路线路进行加固处理时,难免会存在一定的施工难点和风险,所以,选择合理的线路加固方案是有序推进铁路桥涵顶进施工项目的重要环节。本文主要对铁路桥涵顶进施工的线路加固问题进行探讨,并对不同线路加固方案进行综合分析与论述,以期提出更可靠、更科学的线路加固方案。 Under normal circumstances, during the process of jacking construction of railway bridges and culverts, in order to ensure the stable operation of railway lines, the necessary reinforcement of the existing railway lines is often required. When strengthening the existing railway lines, some construction difficulties and risks will inevitably occur. Therefore, selecting a reasonable route reinforcement plan is an important part of pushing forward the construction project of railway bridges and culverts in an orderly manner. This paper mainly discusses the reinforcement of railway bridges and culverts, and analyzes and discusses the reinforcement schemes of different lines comprehensively in order to propose a more reliable and scientific reinforcement scheme for the railway line.
