通过对沈阳市深、浅部构造资料的分析发现,地表NE向断裂十分发育,它们控制了断隆与断凹的形成与发展.在地下7km以上为基岩隆起和凹陷区,与地表构造一致,深部18~20km以上有12条面状铲形正断层,在下地壳有2条深断裂发育.与地表王钢堡-新城子断裂、永乐-清水台断裂相对应的深部F_3断裂和F_6断裂由于其切割深、活动新,可能是关涉沈阳市地震活动的构造.
通過對瀋暘市深、淺部構造資料的分析髮現,地錶NE嚮斷裂十分髮育,它們控製瞭斷隆與斷凹的形成與髮展.在地下7km以上為基巖隆起和凹陷區,與地錶構造一緻,深部18~20km以上有12條麵狀鏟形正斷層,在下地殼有2條深斷裂髮育.與地錶王鋼堡-新城子斷裂、永樂-清水檯斷裂相對應的深部F_3斷裂和F_6斷裂由于其切割深、活動新,可能是關涉瀋暘市地震活動的構造.

The deep and shallow tectonic data in Shenyang and the relationship with the seismic activities show that the developed northeast faults have controlled the formation and the development of the fault-uplift and fault-concave. The uplift and concave of the bedrock below 7 km underground were consistent with the surface structure and two deep faults developed in the lower crust. Because of the deep incision and new activities, the surface Wanggangbao-Xinchengzi fault and Yongle-Qingshuitai fault, which correspond to the deep F_3 fault and F_6 fault, might be related with seismic activities in Shenyang.
