| 摘 要： | 根据压路机-路基结构耦合动力学原理,以压路机振动轮为研究对象,利用动态测试技术,对压实过程中振动轮的响应进行测试,经过信号处理,得到与路基压实质量相关的连续测试参数Cv.通过Cv与常规检测指标的对比分析,验证了动态连续测试指标具有较高的可信度,跟常规指标具有较好的相关性,能客观反映路基压实质量.为实现路基连续同步质量检测提供必要的依据.

| Abstract: | According to the dynamics analysis of the interaction between road roller and subgrade structure,the dynamic continuous compaction control parameter Cv is put forward through dynamic testing technology and system identification theory.Comparison analysis between Cv and conventional test show that the Cv has higher reliability,relationship between the site experiment results and dynamic evaluation indices are established.The results show that the compaction indices Cv give more accurate information about the subgrade compacting state,thus providing an essential basis for the engineering application. |
