摘要:
提取面波频散曲线是面波资料处理中最关键的一步。由于时频分析方法的局限,提出了利用S变换进行瑞利面波频散分析的方法,并给出了具体算法。该方法在时间-频率域中计算相邻两道面波记录同一频率的时间差,再利用道间距除以该时间差来得到该频率对应的相速度,这样避免了在道间距较大的情况下,传统的相位谱法可能造成相位差的缺陷。通过理论模型和实际资料对该方法进行了验证。结果表明,该方法能够提高瑞利面波频散曲线的提取精度,而且算法简单,具有一定的实用性。
Abstract:
Extracting dispersion curve from surface wave is one of the important steps in analyzing surface wave. Because of the limitation of time-frequency analysis, S transform is put forwards to analyzing dispersion of Rayleigh wave and the specific algorithm is shown. Firstly, the method is used to calculate the time difference when two adjacent traces record the same frequency in temporal frequency domain, and secondly, track pitch divided by the time difference is phase velocity of the corresponded frequency. So, it avoids that the method of traditional phase may cause the defect of phase difference in the case of large distance. The method is verified based on theory model and actual data. The results show that it could improve the extraction accuracy of dispersion curves of Rayleigh wave and has some practical.
