中文摘要:
      通过工程实例详细介绍了框架桥顶进的关键工序,综合运用既有线路加固、路基加固、工作坑支护体系施工、框架桥顶进、施工监测等施工措施,保证了既有线路的安全运营和新建工程施工。实践证明这些施工措施行之有效,对以后类似工程具有一定的借鉴意义。
英文摘要:
      Through practical examples of engineering projects, introduced in detail in the present paper are the key processes of the jacking of frame bridges, which involves the application of various construction measures such as the reinforcement of existing railway lines, the construction of the work pit supporting systems, the jacking of frame bridges, construction monitoring and other construction measures in order to ensure the safety of both the operation of the existing railway lines and the construction of projects to be newly built. Engineering practice shows that these construction measures are effective and of certain referential significance for other similar projects in the future.
