摘要:
随着城市轨道交通线路运营年限的不断增长，轨道结构的各种病害逐步呈现，线路的养护维修已成为城市轨道交通维护中的一项重要工作内容。介绍了多个整体道床轨道结构病害处理案例，在此基础上，将整体道床改造需求分为应急抢修、病害治理和环保升级三类，并分析了各自的适用情况。提出了整体道床改造工程的施工特点和实施原则，并针对未来如何更好地实施整体道床改造工程提出了相关建议。
Abstracts:
With the increasing operating years of urban rail transit lines, various diseases of track structure gradually reveal, and line maintenance has become an important part of urban rail transit maintenance responsibility. Several cases of track structure disease treatment of monolithic track bed are introduced, on the basis of which, reconstruction requirements of monolithic track bed are categorized into three types: emergency repair, disease treatment and environmental protection upgrading. Suitable application situations are analyzed respectively. Construction characteristics and implementation principles of monolithic track bed reconstruction project are put forward, as well as suggestions for better carrying out monolithic track bed reconstruction project in the future.
