| 摘 要： | 海底地貌是海水覆盖下的固体地球表面形态的总称。海底地貌巨变往往与海底地质灾害息息相关,会对海底管线和海上平台等海洋工程设施造成危害,因而对海底地貌进行原位观测具有重要意义。本研究基于前人研究成果和团队常年自主研发仪器经验,研制出了剖面声呐海底微地貌原位观测系统,详细介绍了观测系统的组成、功能、工作原理和工作模式,并提出了观测数据的处理分析方法;然后,使用观测系统进行了标志物检验实验,通过将观测系统测量数据与其他设备测量数据相对比,验证了观测系统的可行性和数据准确性;最后,使用观测系统在舟山海域朱家尖滑坡区进行原位观测,进一步验证了观测系统的可行性。观测结果进一步表明剖面声呐观测系统可以用于海底微地貌的观测研究。

| Abstract: | Seabed geomorphology is a general term for the surface morphology of solid earth covered by seawater. Submarine geomorphic changes are often closely related to submarine geological disasters,which will cause damage to submarine pipelines,offshore platforms and other offshore engineering facilities. Therefore,in-situ observation for submarine landform is of great significance. We develop the in-situ observation system of profiling sonar for seabed micro-landform based on previous studies and the team’s years of experiments in independent research and development of instrument. The composition,function,working principle and working mode of the observation system are introduced in detail,and the processing and analysis methods of the observation data are proposed;then,the observation system is used to carry out the marker inspection experiment. By comparing the measurement data of the observation system with the measurement data of other equipment,the feasibility and data accuracy of the observation system are verified. Finally,the observation system is used to observe on the Zhujiajian landslide in Zhoushan sea area, which verified the feasibility of the observation system and showed that the observation system of profile sonar can be used for micro-landform. |
