【摘要】 本文通过研究地震波动方程伪谱法的基本原理,在伪谱法数值正演模拟基础上,结合弹性波动方程的傅氏有限差分逆时深度偏移方法,实现隧道超前预报条件下的波动方程偏移成像。并通过工程应用验证伪谱法数值模拟的可靠度与精确度。更多还原

【Abstract】 An appropriate wave equation numerical modeling method,pseudo-spectral method,is proposed in this article.On the basis of the pseudo-spectral method,a migration method called wave equation Fourier finite difference reverse-time depth method is brought forward to get the migration imagery.Finally,the reliability and the precision is improved by a project example here.更多还原
