介绍了瑞雷波频散计算原理,围绕时距(X-T)域的面波、波频(F-K)的面波和面波的频散特征,详细介绍了瑞雷面波频信号的处理步骤。结合工程实例,分别采用瑞雷波法和环刀法对该路段路基压实度进行检测和对比分析,探讨瑞雷波法检测路基压实度的应用特点及规律,结果表明,二者均取得一致性较好的检测效果,通过瑞雷波方法获取的频散曲线更能如实反映路基压实效果。

The calculation principle of Rayleigh wave dispersion is introduced by surrounding the features ofsurface wave of time interval （X - T） range, wave frequency （F - K） and dispersion of surface wave, and theprocessing step of Rayleigh surface wave frequency signal is introduced in detail. The detection and contrastiveanalysis on the subgrade compaction engineering of this section are made by adopting Rayleigh wave method andcutting - ring method respectively, and the discussion on the application features and laws of the subgradecompaction detection is made by Rayleigh wave method. The results show that, detection effects with betterconsistency are obtained. The dispersion curve obtained by Rayleigh wave method can reflect the subgradecompaction effect truthfully.
