摘要
Abstract
Prior to the construction of an offshore channel,it is necessary to acquire data on the water depth and seabed sediments within the channel,aiming to determine appropriate dredging equipment and processes.Based on the mutual verification of data from existing tidal stations,offshore boreholes,and different exploration technologies,this study determined accurate water depth,seabed topography,and the thicknesses and distributions of sediments in both soft and hard oil layers utilizing the multibeam sounding and sub-bottom profiling techniques.Accordingly,this study summarized the technical measures,as well as the inversion characteristics of soft and hard soil layers of sediments,for offshore channel exploration.The obtained results are beneficial for the economical and efficient offshore channel exploration in sea areas with large waves using the multibeam sounding and sub-bottom profiling techniques.Further-more,these results can be promoted to the exploration of subsea sediments containing toxic substances.关键词
