摘要
本文基于Hencky理论对波动方程重新进行推导,得出震源附近塑性区内地震波的形式与弹性区内地震波的形式一致,只是传播速度有异的结论。它对于地震波的正演模拟将是有意义的。
Abstract
In the light of Hencky theory,wave equation derivation is reperformed. As a result,a conclusion is drawn. That's the seismic waveforms of the plastic area near source are found consistent with that of elastic one but then there are differences in their propagation velocities. Positively,it will be of significance for the forward modelling of seismic wave.
