| 摘 要： | 获取与瑞利波理论频散曲线相匹配的实测频散曲线是正确反演土层参数及分布的前提，表面波谱分析（SASW）法和频率．波数（F-K）法是求取瑞利波实测频散曲线的两种主要方法。采用传递矩阵法计算得到瑞利波在各种典型地层模型地表处时域内的振动信息，作为SASW法和F-K法的测试数据进行了模拟测试。分别将两种方法得到的实测频散曲线与理论频散曲线对比。分析了道距、偏移距和道数等测试参数的影响，以及两种方法对于各种典型地层的测试效果。结果表明，测试参数对两种方法的影响有所不同，选择合适的测试参数能够得到好的测试效果，道数相同时F-K法的测试效果优于SASW法，多通道F-K法的测试效果优于少通道F—K法。

| Abstract: | The spectral analysis of surface wave(SASW) approach and the frequency wave-number(F-K) approach are the two main methods to obtain the tested dispersion curves of Rayleigh wave.Based on three kinds of three-layered ground models,the oscillation information of Rayleigh wave in time-domain at ground surface are calculated by using the transferring matrix method as the simulated testing data for the methods.The influences of the receiver spacing,the source-to-receiver distance and the receiver number to the t... |
