普瑞特实验 Pearce-Pratt Experiment
后者则是用已得到的各层瑞雷波速度值，利用土密度与瑞雷波速的相关关系计算各层的压实度。
Using the latter, with the correlativity of soil 'density and the velocity of the Rayleigh surface wave, we can obtain the compaction of the subgrade.
鉴于瑞雷波勘测技术在工程领域中的应用范围逐渐扩大，并取得了较好的效果，故有必要以瑞雷面波法对路基压实度进行检测，并与常规方法灌沙法和环刀法进行对比，验证其可行性与可靠性。
Given this, it is necessary to detect the roadbed compactness with Rayleigh wave method and compare it with the sand cone method and cutting ring method, which verify its feasibility and reliability.
