摘　　要：介绍了动弹性模量检测设备与原理,探讨了既有线路基基床动弹性模量检测方案和数据处理方法,同时将Evd值大小与路基压实度大小进行了对比,二者之间没有明显的相关性,说明高速铁路路基工程采用多指标控制施工质量是合理的。The article introduces the test equipment and principle. It discusses the dynamic elastic modulus testing scheme of the existing line＇ s bed and its data process method. By comparing with roadbed compaction coefficient and Evd, they have no correlation. It is proved that it is reasonabe for high speed railway subgrade engineering to adopt several parameters to control the quality of the construction.
