    摘要:

    海底地震仪是一种重要的海洋地震观测设备。针对中国近岸浅海洋流噪声大和人类活动频繁的特点,提出链式地震观测方式并对链式海底地震仪节点进行机械结构设计。首先根据内部构件尺寸与布局对地震仪节点整体结构进行设计;然后通过理论计算与有限元仿真方式确定地震仪节点仓体的壳体厚度、端盖厚度和密封尺寸;最后通过压力试验验证所设计的地震仪节点结构的耐压和水密性能符合要求,通过地震观测对比试验验证其接收天然地震的能力。此链式海底地震仪未来将应用于浙江近海的实际地震观测,提供实时连续的地震观测数据。

    Abstract:

    Ocean-bottom seismometers represent crucial marine seismic observation instruments. Considering the loud ocean currents and frequent human activities in China's offshore shallow waters, we proposed a chain seismic observation method and designed the mechanical structure of a cabled ocean-bottom seismometer node. First, the overall structure of the seismometer node was designed based on the dimensions and layouts of its internal components. Subsequently, the hull thickness, end cover thickness, and sealing dimension were determined based on theoretical calculations and finite element simulations. Finally, a pressure test verified the pressure resistance and water tightness of the designed seismometer node structure, while a comparative seismic observation test validated the structure's ability to detect natural earthquakes. Considering these accomplishments, the designed cabled ocean-bottom seismometer is planned to be deployed for actual seismic observations in the offshore area of the Zhejiang Province to gather real-time and continuous seismic observation data.
