摘要
主要研究了地震瞬态瑞利波频率—波数域频散曲线的提取,以二维傅氏变换,半波长理论等作为理论基础。使用Delphi7.0将其程序化,通过工程应用验证了本方法及程序。结论证明f-k方法克服了一维数字处理技术存在的不足,充分利用了多道瑞利波数据记录信息。
Based on two-dimensional Fourier transform and half-wave theory,this paper has studied the seismic Rayleigh wave dispersion curve extraction in f-k domain and made this theory fit in with a program by means of Delphi7.0.It is concluded that the f-k method overcomes the shortcomings of the one-dimensional digital processing technology and makes full use of multi-channel Rayleigh wave data record.
