| 摘 要： | 高速铁路施工中同时采用了K30、Ev2、Evd3项力学指标对路基压实质量进行检测,该3项指标的检测内容与检测原理接近.为了减少检测工作量、提高检测效率,本文在简要分析3项指标各自测试原理的基础上,利用大量实测数据,对3项指标进行了相关性分析.分析结果表明,3项指标具有较好的相关性,且用回归分析结果反算的数值与规范给出的标准相近,说明该3项指标具有较好的相互替代性.依据分析结果,认为用Ev2替代K30,或用Evd替代Ev2和K30都是可行的.

| Abstract: | There are three indexes K30,Ev2,Evd which are used simultaneously to test the quality of the high speed railway roadbed.The indexes make the testing job very hard because of their strictness.In order to simplify the testing work,the paper analyzes the correlation of the three testing indexes based on a large number of site test data.The results of analysis indicate that there is good correlativity among the three indexes,and the values of indexes obtained through the regression curve are very close to the standard values. It is better to use Ev2 to substitute K30,or use Evd to substitute Ev2 and K30. |
