| 摘 要： | 在文献[1]的基础上详细讨论了各台站直达波初动震相清晰度存在差异时如何利用井下和地面观测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。理论和实际检验表明,对于一个台网而言,考虑各台站震相清晰度间的差异,会使定位主要依赖于震相清晰的台站的资料,而震相不太清晰的台站的资料只对定位起参考作用。从而提高了整个台网定位的可信度。

| Abstract: | Based on the previous paper 1,in this paper,an optimum method for determining thesource location,origin time and average regional wave velocity is discussed by using thedata of direct wave arrival time recorded both in the deep well and on the ground when dif-ferent clearness of direct wave phase in every station is considered.It is indicated through the-oretical and actual calculations that the result of localization greatly depends on the arrivaltime data of clear phases by considering difference of seismic phase clearness in a network ofstation,the data of fuzzy phases are for reference only. |
