针对现行路基压实质量评价指标的不足，基于连续压实控制技术的基本原理，通过对压路机振动轮与路基结构相互作用的动力学分析，把拾振传感器采集到的振动轮加速度信号经过放大、滤波等处理，并经模数转换后将模拟信号变为数字信号，把这种经过处理后的振动轮加速度信号作为连续压实测试指标——振动压实值（VCV），提出将其作为路基连续压实质量的评价指标，实时判断路基压实质量。通过对两个试验路段的VCV和平板载荷类常规指标地基系数K30、动态变形模量Evd、变形模量EV1和EV2的对比分析，结果表明，振动压实值与平板载荷类常规指标间存在着线性相关关系，据此可以根据常规指标的压实标准确定连续压实测试指标的控制标准，为连续压实路基质量的检验和控制提供了依据。

The indies currently used for evaluating the compaction quality of railway subgrade are not sufficient for evaluation. Based on the fundamental theory of continuous compaction control, a kinetic analysis of the interaction between the roller’s vibrating wheel and the subgrade structures is performed, and the acceleration signals of the vibrating wheel, which was collected by collecting vibration frequency sensor, are analyzed by magnifying, filtering and other treatment; through analogue-digital conversion, the analogue signals are converted to digital ones. The treated acceleration signal of the vibrating wheel is used as the measuring index for continuous compaction–vibrating compaction value (VCV), to evaluate the real-time compaction quality of the subgrade. By comparing and analyzing the VCV and regular indexes of K30, Evd, Ev1 and Ev2 under category of plate loadings, which were obtained from two testing sections of high speed railway, it is revealed that, the continuous compaction index has a linear relationship with the regular index under category of plate loadings. Therefore, the control standard for vibrating compaction value can be determined with the compaction standard of the regular index, providing a basis for the inspection and control of the continuous compaction of subgrade.
