摘要
武汉至广州客运专线铁路设计时速为350km，采用无砟轨道结构。客运专线对线下工程的技术标准提出了更高的要求，路基施工质量控制是其中的重点和难点课题之一。文中根据武广客运专线路基工程的实际施工经验，阐述了路基填筑施工方法、施工控制要点和路基压实检测方法，总结了路基填筑施工工艺流程。检测结果，路基各项指标均满足规范要求，效果良好。
Wuhan-Guangzhou Passenger Dedicated Line, with design speed of 350km, adopts ballastless track structure. Passenger dedicated line has higher requirement for technical standard of underline engineering, of which, subgrade construction quality is one of the stresses and difficulties. Based on practical experience of subgrade engineering of Wuhan-Guangzhou Passenger Dedicated Line, this paper describes subgrade filling method, construction control points and subgrade compaction detection method, and summarizes subgrade filling process flow. It is indicated from result that each indicator of subgrade meets specifications with good effect.
