武广客运专线V标段路基施工对策

控制地基的工后沉降是控制路基工后沉降的关键。结合武广客运专线V标段实际，针对地质和地形条件（岩溶地基、软土和一般地基路基、低路堤地基、过渡段路基等）的不同，提出不同形式的加固方式，并总结出了武广客运专线V标段路基施工对策，即充分了解地基地质条件，建立全面路基变形监测系统，实现路基动态施工，对高速铁路路基的施工具有一定的指导意义。

On the Countermeasures of Contract Section V Subgrade Construction in Wuhan-Guangzhou Passenger Dedicated Railway

Controlling the post-construction subsidence of the groundsill is the key of controlling the post-construction subsidence of the subgrade. This thesis, combined with the practice of Contract Section V in Wuhan-Guangzhou Passenger Dedicated Railway, targeting at the difference in geology and topographical conditions （karst foundation, soft soil and general foundation subgrade, low embankment subgrade, transitional subgrade, etc. ）, put forward multi-form treatment and strengthening method, and summarized ＂Countermeasures for Contract Section V Subgrade Construction in Wuhan-Guangzhou Passenger Dedicated Railway＂, that is, to fully understand the geological conditions of the foundation; to set up an overall subgrade deformation monitoring system in order to realize the dynimic monitoring of the subgrade construction. It has certain directive significance to the construction of the roadbed in high-speed railways.
