某高速铁路路基段无砟轨道出现上拱病害，且平面上有一定量的偏移，经深入分析，主要原因为路基
基岩在构筑过程中应力重分布作用下的缓慢蠕变。目前该病害尚无根治措施，为整治该段因上拱引起的限
速，决定在线拆除并重构无砟轨道。本文提出的营业线天窗时间内进行无砟轨道重构整治方案，不断道限速
运行，方案可行，效果良好，相关施工经验可为同类工程提供参考。
- Abstract:
-
The ballastless track in the subgrade section of a high-speed railway had the arch disease，and there was a
certain amount of offset on the plane. After in-depth analysis，the main reason was identified as the slow creep of
subgrade bedrock under the effect of stress redistribution during construction. Currently，this disease can not be cured
once and for all. In order to solve the speed limit problem caused by the arch disease of this section，the ballastless
track was dismantled and then reconstructed in an online manner. This paper provides a scheme of reconstructing the
ballastless track within the skylight time of the operating line while keeping the line operating at a limited speed. This
scheme is proven feasible，with good effect，and the construction experience can provide a reference for similar projects.
