【摘要】：基于團(tuán)隊(duì)自主研發(fā)的高密度電阻率探桿,將變點(diǎn)分析理論中的局部比較法,引入到高密度電阻率探桿觀測(cè)數(shù)據(jù)分析處理中,以實(shí)現(xiàn)海床界面位置的自動(dòng)判別,并應(yīng)用該套裝置與方法在遼東灣東部某海域進(jìn)行了海底床界面動(dòng)態(tài)變化的原位實(shí)時(shí)監(jiān)測(cè)。通過(guò)將電阻率的判定結(jié)果與目前應(yīng)用普遍的聲學(xué)方法同步記錄的結(jié)果進(jìn)行對(duì)比,分析發(fā)現(xiàn):電阻率探桿測(cè)量結(jié)果與聲學(xué)侵蝕儀記錄結(jié)果具有良好的一致性與同步性,局部比較法能夠較為理想地從高密度電阻率探桿的觀測(cè)數(shù)據(jù)中獲取海床界面的動(dòng)態(tài)變化過(guò)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.
