摘　　要：通过在武广高速铁路路基填筑现场对压实质量控制参数进行对比试验,得出了对地基系数K30与变形模量Ev2、动态变形模量Evd与变形模量Ev2大致的相关关系,提出了与地基系数K30相匹配的变形模量Ev2压实标准,并对压实标准的物理指标、K30试验方法提出了修改建议,可为铁路路基相关规范、标准的制修订提供参考。On the basis of comparative experiments on compacting quality control parameters of subgrade filling for Wuhan-Guangzhou high speed railway, the approximate correlation between the coefficient of soil reactionK30 and the modulus of deformation Ev2, and that between the dynamic deformation modulus Evd and the modulus of deformation Ev2 is obtained, and the compaction criteria for Ev2 matching with K30 is put forward. Suggestions on modification of physical index of compaction criteria and the experimental method for K30 are given, which may be used as reference for development or revision of relevant codes or standards on railway subgrade.
