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。
By comparing the compaction quality control parameters with the parameters of compaction quality control at the site of embankment of Wuhan-Guangzhou high-speed railway, the correlation coefficient between foundation coefficient K30 and deformation modulus Ev2, dynamic deformation modulus Evd and deformation modulus Ev2 is obtained. And the deformation coefficient Ev2 compaction standard which is matched with the foundation coefficient K30. Some suggestions for modification of the physical index of the compaction standard and the K30 test method are also provided, which can provide reference for the revision and revision of the relevant norms and standards of railway subgrade.
