| 中文摘要:唐包铁路线白草鞍隧道无砟轨道上行线局部线段轨道板渗水、翻浆，在列车动荷载作用下发生不均匀下沉。对轨道板下沉病害进行了注浆、注胶整治施工：向下沉悬空轨道板线段仰拱下0.5 m垂深破碎岩层压注速凝水泥浆以达到密实和固化拱底破碎岩层改善和提高仰拱基底岩石承载能力，向已下沉的轨道板底压注新型高强度发泡树脂4.75#双液胶体以提升整体轨道板直至恢复其原位。经注浆、注胶技术处理，该线段垂向下沉量达到了设计稳定值，恢复无砟轨道运载能力。 |

| Abstract:There was water seepage and frost boiling in the track plate at the local uplink of the ballastless track of Baicaoan Tunnel of the Tangbao railway line. Under dynamic loading of trains， the track plate sank unevenly. Railway track plate sinking was treated by grouting and glue injection： The 0.5m vertical depth of the broken rock layer under the inverted arch of the suspended track plate was injected with quick-setting cement slurry to achieve compaction and solidification of the broken rock layer at the bottom of the arch to improve and increase the rock bearing capacity of the base of the inverted arch； and a new 4.75# high-strength foamed resin was injected into the bottom of the sinking track plate to lift the whole track plate until it returns to its original position. After grouting and glue injection， the vertical subsidence of the line has reached the designed stable value with the carrying capacity of the ballastless track restored. |
