摘　　要：无砟轨道在运营过程中受到各种因素的耦合作用,部分线路出现不同程度的病害。随着无砟轨道运营里程的增加,无砟轨道病害问题亦变得突出。本文总结了现有隧道内无砟轨道主要病害形式及其常用整治措施。重点阐述了某客运专线隧道内出现的无砟轨道上拱病害情况、隧道地质情况及目前已实施的治理方案,并提出了若病害继续发展可采用的维修方案,可为同类工程问题提供借鉴。The ballastless track is coupled by various factors during operation, some lines are damaged to varying degree. With the increase of operation mileage of ballastless track, the disease of ballastless track is increasingly outstanding. The main diseases forms of ballastless track in tunnel and common maintenance measures are summarized in the paper. The diseases on the crown of the ballastless track in tunnel of a passenger dedicated line, geological conditions of tunnel and currently implemented maintenance measures are represented as emphases. Maintenance measures are proposed if the diseases go worse which can provide references for similar engineering problems.
