沈阳市活断层深地震反射勘探研究

Research on the Deep Seismic Reflection Exploration of Active Faults in Shenyang City

本文通过深地震反射探测,获得了沈阳市区北部Moho面以上的地壳深部结构和剖面,上地壳复杂的断裂组合关系和下地壳高角度的深断裂共同构成了该区的深、浅构造关系,其结果为沈阳市活断层的地震危险性评价奠定了基础。

The deep crustal structure and profile above Moho surface in the north area of Shenyang are studied by deep reflection exploration. Both of assorted relation of complicated faults at the upper crust and the high-angle deep faults at the lower crust constitute the structural relation between the deep and shallow parts of the region. The achievement of this paper has established the base for the seismic risk evaluation of active faults in Shenyang city area.
