回顾了瑞雷面波勘探技术的发展历史,介绍了主动源瞬态面波的互相关法、表面波谱分析法、相位展开法、τ-p变换法、Prony法、多道面波分析法等处理法,被动源面波(微动)的空间自相关法、频率波数法、HV谱比法、折射微动法等处理方法,分析了各种方法的优缺点以及适用条件。结果表明,主动源和被动源面波法可确定横波速度结构,其应用领域非常广泛;主动源和被动源面波联合勘探,使用不同的方法处理后在频率相速度域合并,可以得到高精度的频散曲线,有效提高勘探的横向分辨率和纵向深度,具有广阔的应用前景。

The paper firstly reviews the history of the Rayleigh wave exploration technology.Then it introduces various methods of SASW,τ-p transform,Prony,MASW,SPAC,F-K,H-V and REMI.In addition,it analyzes the advantages and disadvantages of each method.The results show that active source and passive source wave method can determine the s-wave velocity structure,so its application is very wide.Furthermore,joint exploration of active source and passive source surface waves and dispersion curve combination can obtain the high precise dispersion curve,which has a broad applied prospect because it will efficiently improve horizontal resolution and vertical depth of the exploration.
