THE SIGNAL MODEL IN TRANSIENT RAYLEIGH WAVE PROSPECTING AND THE CORRECTION OF ITS PHASE VELOCITY

摘要: 在网络分析的基础上,将瑞雷波探测的A道信号作为一网络的输入,B道信号作为其输出,给出A、B两道的最一般信号模型,解释了目前瞬态法信号计算相速度及其频散曲线与稳态信号相速度及其频散曲线差异的实质。提出了瞬态瑞雷波相速度的改进算法。结果表明,校正后的相速度有明显的降低,其频散曲线的分辨率有所提高。

Abstract: By using the network theorem, the authors consider that one of both sensory channels in transient Rayleigh wave prospecting is taken as the input node of a network, the other as the output node. An universal signal model of both channels is provided, the substance of difference between the phase velocities and their dispersion curves calculated both by the transient source and stable source are interprated. The improved algorithm of the phase velocity of transient Rayleigh wave is provided. The result indicates that the corrected phase velocity is decreased obviously, and the resolution of its dispersion curve is somewhat increased.
