摘要
本文摘要地论述了瞬态瑞雷波勘探的原理，分析了影响瞬态瑞雷波勘探的各种因素以及应采取的数据采集技术。结合实例初步探讨了几种数据处理对频散曲线计算的影响，以及互谱法求取相移对面波频散曲线计算精度的影响问题，最后讨论了频散曲线中出现的三种异常特征及其产生的原因。
The present paper has dealt with the principle of transient state Rayleigh wave elploration, and analysed various factors affecting transient state Rayleigh wave exploration and the datacollecting technique tEat should be adopted. With practical examples. the paper Las tentatively probed into the effects of several sorts of data-processing upon frequency dispersion curve calculation.and the influence of evaluating phase deviation by mutual spectral method upon the precision of surface wave frequency dispersion curve calculation. Finally, characteristics of three sorts of anomalies that appear in the frequency dispersion curve and the causes for their formation are discussed.
