APPLICATION OF SEAFLOOR ACOUSTICS IN MARINE ENGINEERING GEOLOGY

The theory and methods of seafloor acoustics play a significant role in the development of marine engineering geology. Basing on the latest research progresses of the seafloor acoustical theory including seafloor sound proprogation model and seafloor sound reflection and scattering model and the seafloor acoustical methods including field investigation, in-situ observation, and laboratory experiments, this paper demonstrates the application and contribution of seafloor acoustics in marine engineering geology in the four aspects incuding marine engineering geological zoning, seabed sediment property inverting, field investigation of marine engineering geological hazards, and in-situ observation of marine engineering geological process. The summary on the close realationship between seafloor acoustics and marine engineering geology in this paper is being conducted to provide guidance to the application of seafloor acoustics in marine engineering geology in future.
