Based on the principle of Rayleigh wave test, it introduces the testing method to detect compactness of subgrade, and provides the experiment equipment and detection process.
根据瑞雷波法的检测原理，介绍了其在填土路基密实度无损检测中的设备组成和检测步骤。

The dispersive characteristics of the Rayleigh waves propagated in the layered media are investigated experimentally by ultrasonic detection test, especially in the presence of a low-velocity layer.
通过超声实验研究了沿分层介质，特别是含有低速层的分层介质传播的瑞利波频散特征。
