基于边界元法的地震波方程时间域数值模拟

Time-domain Simulation for Seismic Wave Equations Based on Boundary Element

研究了复杂地下介质情形地震波传播的数学模型,讨论了地震波数学模型数值求解的时间域边界元方法,构建了两个理论上的地震勘探模型并进行了合成地震记录的数值模拟计算。

In this paper, the authors study the mathematic model for seismic wave propagation in complex underground medium, discuss the boundary element method for solving seismic wave equations in time-domain, establish two theoretical seismic exploration models, and implement numerical simulation so as to obtain the synthetic seismograms.
