| 摘 要： | 为指导渤海海峡跨海通道工程的建设,利用穿过渤海海峡的多条单道地震剖面和多道地震剖面,详细研究了该区的新构造运动特征。结果表明:渤海海峡活动断裂发育,以NW和NE向为主,表现为同生性和集束性;浅层气发育,与蓬莱油田具有较好对应关系,显示其为深层来源;新构造期岩浆活动与区域活动断裂也具有较好的对应性。影响渤海海峡工程建设的灾害地质较发育,跨海通道的建设难度巨大,应进行严格详细的评价,并采取安全避让措施。

| Abstract: | The characteristics of neotectonic movement around the Bohai Strait are researched upon the comprehensive study of some newly collected seismic profiles, including both single and multiple channel seismics. Data reveals that there are intensive neotectonic movement and various geohazardous factors in the study area such as fracturing, shallow gas and magmatic activities. The NE-striking fault and NW-striking fault are the main active faults. The shallow gas is popular and deep in origin. The magmatic activity are well coupled with fault activities. Some suggestions are made for future engineering constructions. |
