Abstract

On the basis of studying water-sediment movement in the Lingdingyang sea area, sedimentation characteristics of the trial dredged-trough of immersed tube tunnel of HZMB are analyzed, with 17 groups of underwater topographic survey data and the measured results of fluid mud and silt unit weight in the base trough and slopes. And some results are obtained, including siltation rate changes and its distribution characteristics of the trial dredged-trough, the slope ratio of steady slope, the thickness and its trends of the fluid mud layer and silt layer in the trough. This paper analyzes the statistics of ultrasonic depth-sounding with three different frequencies, and it’s found that there is a difference of 0.3m between multi-beam and low frequency, which coincides with the measured values of the fluid mud thickness of 0.29m very well.
