地下爆炸地震波的数值模拟及震源函数的研究

摘要

利用广义反射、透射系数矩阵和离散波数方法，计算了水平分层花岗岩介质中近场(十几公里)范围内三次地下爆炸的地表粒子速度垂直分量波形，并通过对实测波形的拟合，得到了地下爆炸激发的地震震源函数。%Vertical surface particle velocity waveforms recorded within 15kmfrom three underground explosion centers were simulated.Effective source functions were obtained from recorded and calculated waveform.
