摘要
以简化试验监测数据、提高施工效率为目标,针对京沪高速铁路控制路基压实指标中的变形模量Ev2和地基系数K30两个力学指标作了相关性分析,结果表明,Ev2和K30的回归曲线相关性较高,利用得出的回归曲线,取规范中规定的Ev2值计算得到的K30值与规范值的偏差较小,说明规范中要求的K30和Ev对路基压实质量的控制标准相当。
In order to simplify test monitoring data and improve construction efficiency,pointed to the compaction indicators of deformation modulas Ev2 and foundation coefficient K30 in Beijing-Shanghai High Speed Railway,the paper carried out the correlation analysis.The results showed that Ev2 and K30 have high correlation in the regression curve.Using the regression curves can obtained Ev2 value asstipulated in the regulation,and then calculated K30 value has smaller deviation with standard ralue.This explained that the required of K30 and Ev2 in the regulation are appropriate to subgrade compaction quality control standards.
