近期完成的北北东向的繁峙～太仆寺旗宽角反射／折射剖面，由山西断隆进入内蒙地轴，它穿过了山西地震带的大同～阳高震区和北西西向张家口～渤海地震带的西北缘。其主要目的是探测研究张～渤地震带及其两侧壳幔构造与速度结构的差异及其与地震活动的相关性。结果表明：张～渤地震带壳内界面及莫霍面较其两侧有１．０～２．０ｋｍ的不同程度的上隆；在阳原～张家口之间地壳结构纵向与横向非均匀性明显，上地壳和下地壳上部有局部的速度逆转，下地壳下部的低速层由山西断隆一直延伸至内蒙地轴，上地幔顶部的速度梯度明显增大；在阳原、怀安和张北附近分别存在着延伸至莫霍面的地壳深断裂带；在内蒙地轴一系列壳内界面不明显。
The recently completed North-to-East Fanzhi ~ Taipusi Banner wide-angle reflex / refraction profile, from the Shanxi off into the Inner Mongolia axis, it passes through the Shanxi earthquake zone Datong ~ Yanggaozheng area and the North West to Zhangjiakou ~ Bohai Sea seismic belt Northwest edge. Its main purpose is to investigate the differences of crust-mantle structure and velocity structure and their correlation with seismicity in Zhang-Bohai seismic zone and its two sides. The results show that there are some 1.0 ~ 2.0km uplift in the crustal interface and the Moho in the Zhang-Bo earthquake zone, and the vertical and horizontal inhomogeneities of crustal structure between Yangyuan and Zhangjiakou are obvious , The upper crust and the upper crust had local velocity reversal. The lower crust beneath the lower crust extended from the Shanxi fault to the Inner Mongolia axis, and the velocity gradient at the top of the upper mantle increased obviously. In the vicinity of Yangyuan, Huai'an and Zhangbei There is a crustal deep fault zone that extends to the Moho. In the Inner Mongolia, a series of intracrystalline interfaces are not obvious.
