【摘要】：基于团队自主研发的高密度电阻率探杆,将变点分析理论中的局部比较法,引入到高密度电阻率探杆观测数据分析处理中,以实现海床界面位置的自动判别,并应用该套装置与方法在辽东湾东部某海域进行了海底床界面动态变化的原位实时监测。通过将电阻率的判定结果与目前应用普遍的声学方法同步记录的结果进行对比,分析发现:电阻率探杆测量结果与声学侵蚀仪记录结果具有良好的一致性与同步性,局部比较法能够较为理想地从高密度电阻率探杆的观测数据中获取海床界面的动态变化过程。
[Abstract]:Based on the high-density resistivity probe developed by the team, the local comparison method of the change point analysis theory is introduced into the analysis and processing of the observation data of the high-density resistivity probe, so as to realize the automatic identification of the interface position of the seabed. The dynamic changes of seabed interface in a certain sea area in eastern Liaodong Bay were monitored in situ by using the apparatus and method. By comparing the determination results of resistivity with the results of synchronous recording with acoustic methods widely used at present, it is found that the measured results of resistivity probe and the results recorded by acoustic erosion instrument have good consistency and synchronism. The local comparison method can obtain the dynamic change process of the seabed interface from the observation data of the high density resistivity probe.
