摘要
本文详细讨论了利用井下和地面观测直达波到时资料联合确定震源位置,发震时刻及区域平均波速的最优化方法,该方法对震源深度及波速的确定给予特别的重视与处理。理论检验和实际算例表明,用该方法编制的程序定位精度高,计算速度快,可以在地层差异小的地区推广应用。
In this paper, based on the combined direct wave onset times recorded both in the deep well and on the ground the optimum method for determining the source location, origin time and average regional wave velocity has been studied. The method considers greatly the source depth 'and velocity determination. It is indicated through the theoretical and actual calculations that, with the program designed by the method the obtained result is of high location precision and quick velocity calculation, so that the method might be applied in the area where the stratum difference is low.
