断裂活动性研究是一个与地质学、地震学和工程学有密切关系的课题。辽东半岛的断裂比较发育,位于复县西部沿海的东岗断裂只是其中的一条。由于它处于辽宁核电站的预选厂址内,加上对其活动性的认识有分歧,所以查明断裂的活动性十分重要,它直接涉及该预选厂址是否能建核电站。近年来,就东岗断裂的活动性开展了地震地质、第四纪 Research on fault activity is a topic closely related to geology, seismology and engineering. The fault in Liaodong Peninsula is relatively developed, and the Donggang fault on the western coast of Fuxian County is only one of them. Due to its disagreement on the pre-selected site of Liaoning’s nuclear power plant and the disagreement on its activity, it is very important to identify the activity of the fracture and it is directly related to whether the pre-selected site can build a nuclear power station. In recent years, the activity of the Donggang fault has carried out seismic geology and Quaternary
