摘要
波动方程法地震波正演数值模拟主要包括有限差分法、连续有限元法,谱方法以及新兴的间断有限元法。本文总结了这些方法近年来的新进展,探究了各方法在应对起伏地表等复杂构造和提高模拟效率等方面出现的新技术,并对该领域的发展方向和趋势进行了分析和展望。
The wave equation methods of the seismic forward numerical simulation include finite-difference method, continuous finite-element method, and spectral method and newly presented discontinuous Galerkin finite-element method. The paper summarized the progresses made on these methods in recent years, researched the new techniques to deal with complex structure and improve efficiency of simulation, and analyzed the direction of the development of the technique in this domain.
