摘要: 菏泽一长治地震测深剖面探测研究的目的是为了揭示菏泽地震区、东明坳陷、汤阴地堑、林县微震区、太行山和山西高原南部等构造的地壳结构特征及其与矿产资源、地震活动的关系。该剖面测深资料以往已作过分析处理,取得了一些初步成果。本文是在原解释分析基础上,进一步收集沿剖面的地质、地球物理资料,采用任意非均匀二维模型设计,运用动力学射线追踪原理编制的"SEIS83"程序进行走时和振幅计算,并对某些波组震相进行了较深入的讨论、计算,取得了一些很有意义的结果。Abstract: The Heze-Changzhi DSS profile aims at studying the relation of seismic activity and mineral resources to the structural property of crust in Heze earthquake region, Dongming depression area, Tangyin groben, Linxian microearthquake region, Taihang mountain area and the southern part of Shanxi plateau. The data from this profile had been analyzed and some preliminary results were obtained previously. On the basis of the the previous results, we colleted further the geological and the geophysical data along the profile and calculated the travel time and amplitude by the program SEIS83 compiled with the dynamic ray trace principle in 2-D inhomogeneos model, we also discussed and calculated deeply some special seismic phases and got some results of great significance.
