几类各向异性介质中震源的数值模拟

Numerical Simulation of Seismic Origin on Several Classes Anisotropic Media

本文根据弹性理论中的几个基本方程。导出弹性均匀各向异性中的Christoffel 方程。及由此得出地震波的传播速度与介质的弹性参数间的数值关系,并利用有限元法计算出波场.

From several basic equations in elastic theory,the Christoffel equation about elastichomogeneous anisotropic media is derived,so the numerical relation betweenpropagation velocity of seismic wave and elastic parameters of media is gained,andthe wave field is calculated by finite element method.
