基于海上风电工程建成了涵盖测震、强震动、电磁和GNSS等多学科交叉、多技术应用、多手段融合的江苏近海地震综合观测台网。以中国台湾宜兰县海域6.6级地震记录为示例,分析了各类典型台站获取的地震记录,结果表明:海上风电工程平台站、海底站以及DAS站均能获取清晰的地震记录,震相清晰,能够准确识别P波和S波到时信息。其中,平台站加速度记录时程和频谱分析表明,海上风电工程结构对地震动具有显著的放大作用,能够有效反应工程结构在地震作用下的动力响应特征。实时传输、高采样率的海底电磁观测数据有效率逐步提升。通过对观测数据的初步分析,验证了基于海上风电工程的近海地震观测技术方案可行,观测数据质量可靠,提升了我省海洋地震监测台网孔径,拓展了海洋地震安全服务范围,为下一步开展海上风电现地预警和区域预警相融合的地震预警研究以及结构安全评估研究奠定了技术基础。
Based on offshore wind power projects
a comprehensive offshore seismic observation network was constructed in Jiangsu
integrating multiple disciplines
technologies
and methodologies
and covering seismometry
strong-motion monitoring
electromagnetism
and GNSS. Taking the records of the
M
6.6 earthquake in the offshore area of Yilan County
Taiwan
China as a case study
this study analyzed seismic records collected
by various typical stations. The results showed that offshore wind power platform stations
seafloor stations
and DAS stations were all capable of capturing clear seismic records with distinct phases
enabling accurate identification of P- and S-wave arrival times. In particular
time-history and spectrum analyses of acceleration records from platform stations indicated that offshore wind power project structures exerted a significant amplification effect on ground motions
and could effectively reflect the dynamic response characteristics of the engineering structures under seismic action. The validity rate of real-time
high-sampling-rate seafloor electromagnetic observation data was steadily improving. Preliminary analysis of the observation data verified the feasibility of the offshore seismic observation technical scheme based on offshore wind power projects and the reliability of the observation data quality. This scheme expanded the coverage of Jiangsu Province's offshore seismic monitoring network and extended the scope of offshore seismic safety services
thereby laying a solid technical foundation for future research on the integration of on-site early warning and regional seismic early warning as well as structural safety assessment for offshore wind power facilities.
