【摘要】 在邢台地震区开展了地震转换波测深工作，得出了６条深部构造剖面图，其中包括３条ＮＷ向和３条ＮＥ向剖面，同时也得出了地壳内Ｇ、Ｃ和Ｍ３个主要深部界面的埋深分布图以及地壳内波速分布模型。在此基础上讨论了邢台强震发生的深部三维构造背景和深部孕震条件。更多还原

【Abstract】 A deep sounding work by converted waves of earthquakes has been conducted in Xingtaiearthquake region. As a result, 6 cross-sections of deep structure in Xingtai earthquake area havebeen constructed (3 in NW trend and others in NE trend). On the bases of these sections thestructures of major deep crustal interfaces G,C and M were determined. At the same time, thevelocity models of P and S waves were constructed. Moreover, background of 3-D deep structureand the dynamic conditions for earthquake occurrence are also discussed.更多还原
