【摘要】 在横向非均匀的复杂地壳结构中,地震波的理论走时和理论地震图的计算一般借助于射线近似法。基于上述理论,本文探讨了由人工地震资料反演横向非均匀的地壳结构的方法和步骤。反演过程中,综合考虑了波的运动学特征和动力学特征。以任县—武清剖面的资料处理为例,说明了该方法的实际应用。更多还原

【Abstract】 In this paper, it is suggested to use the approximate ray theory (ART) to get the theoretical traveltimes of seismic waves and synthetic seismograms in laterally heterogeneous crustal model. Based upon that, a discussion on the methods and procedure of DSS data inversion in the model has been preliroinarily made. It is necessary to consider both kinematic and dynamic characteristics in the data processing. The data processing of Renxian-Wuqing DSS profile has been taken as an example to illustrate the practical application of the above mcthods.更多还原
