摘　　要：海洋地震监测是防震减灾的重要工作内容之一,是提高海域中地震定位精度、监测水平的技术手段,并可为大地构造、地球动力学等基础地学研究提供宝贵基础信息。根据国内外海洋地震监测技术发展现状,结合现代海洋资料浮标与海底光缆技术特点,文中着重探讨基于三锚式大型浮标平台的海洋地震监测技术与方法。研究分析表明:建设基于海洋浮标平台的地震监测系统更具可行性、可操作性,采用直径三锚式大型浮标作为“通讯和供电子系统”较为适宜;海洋地震监测项目的安全关系到了整个系统的稳定运行,特别要关注“通讯和供电子系统”和“地震观测技术子系统”之间连接的安全保障措施;海洋地震监测项目质量对保障整个系统具有举重轻重的作用,在“地震观测技术子系统”海底安装中要注意地震设备的防洋流和与大地耦合的两个重要环节。Marine seismic monitoring,one of the most important contents of earthquake prevention and disaster reduction,is a technical methodology to improve the positioning accuracy and monitoring capacity of earthquakes in the sea area,and can provide valuable basic information for basic geological research such as geotectonics and geodynamics.Based on the development status of marine seismic monitoring technology at home and abroad,by combining the technical characteristics of modern marine data buoys and submarine fiber-optic cables,this paper focuses on the marine seismic monitoring technology and method based on three-anchor large buoy platform.The study shows that it is more feasible and operable to construct the seismic monitoring system based on marine buoy platform,and it is more suitable to use three-anchor diameter large buoys as the"communication and electronic supply system".The research has also shown that the security of the marine seismic monitoring project is related to the stable operation of the entire system,and the safety and security measures for the connection between the"communication and electronic supply system"and the"seismic observation technology subsystem"should be paid special attention to.The quality assurance of the marine seismic monitoring project is related to the completion of the whole system.In the submarine installation of the"seismic observation technology subsystem",attention should be paid to the two important aspects of protection against ocean currents and earth coupling of seismic equipment.
