摘要
本文以水平层状液体为模型,推导出瑞利面波的频散方程,进而作了多层介质的模型试算并绘出了瑞利波波速与波长的关系曲线。该曲线对应于弹性分界面上的异常特征与实测曲线的异常特征吻合,可用于说明层状介质中瑞利面波勘探的机制。文中还以理论模型试算结果为依据,对当前面波勘探中的半波长解释方法作了评述,并解释了固体层状介质中面波曲线的异常特征。

In this paper dispersion equations of Rayieigh waves are derived on the
basis of a horizontal layered liquid model. Furthermore, calculation on multi-
layered media is made and curves of Rayleigh wave velocity with respect to
wavelength are drawn. Anomaly characterstics on the curves, which correspond
to elastic subsurfaces, agree well with those on curves measured in practice,
and reasonably show the mechanism of exploration in layered media by Reyleigh-
wave technique. With calculations of the theoretical model, the authors also
offer comments on the hail-wave-length interpretation method which is cur-
rently used in surface wave exploration and explain the anomaly characteristics
on curves recorded from solid layered media.
