摘　　要：本文结合对辽宁省大东港地震基本烈度复核工作,利用实测重力资料,对港区及其附近地区的重力异常变化进行了初步研究.实践证明,重力勘探确定鸭绿江断裂穿过东沟盆地由前阳山继续南延及查明港区的构造稳定性,有着显著的效果.Combining with the check of seismc intensity, we studied gravity anomalies in Dadong port area and near regions of Liaoning province with gravitative observation data. Present study shows that Yalu rivert fault cuts across Donggou basin and extends to south We also tindf that geologic tectonic in Dadong port is stable.
