地震爆炸震源模拟

The simulation of seismic explosive source

本文通过把地震于波产生分为两个阶段，即冲击波的形成和冲击波的传播，来模拟从爆炸到地震于波形成的过程，并研究通过低速带传播后的地震子波的频率变化。这对于如何设计最优的激发条件和客观地提高地震记录的分辨率有一定的参考价值。

By classifying the generation of seismic wavelet into two stages, i. e. the forming of shockwave and the propagation of shock wave, we simulate the procedure from the explosion to theseismic wavelet generation- And we study the frequency variation of seismic wave1et propagated inlow vel0city zone- This has reference value for designing the optimal excitation condition andobjectively improving the res0lution of seismic records.
