摘要：
     加筋垫层的设计对于桩-网结构路基来说至关重要，而确定土工格栅的强度又是加筋垫层的设计重点。现结合遂渝线土质路基上修建的无碴轨道综合试验成果，对桩-网结构路基加筋垫层设计进行深入的探讨，为类似工程设计提供参考。

Abstract: The reinforced earth layer is very important to the performance of columngeogrid reinforcement in the embankment. The determination of the geogrid strength is the key to the proper reinforced earth layer design. The design approach of the columngeogrid reinforcement in a comprehensive test embankment section for the ballastless track for the SuiYu high speed rail is thoroughly discussed in this paper.
