摘要Grain size parameters are the basic elements to describe and express seafloor sediments, which deeply influence acoustic and physical-mechanical properties of seafloor sediment. Statistical analysis of the results in the paper indicates that several parameters in graininess of the seafloor sediments, including porosity, dry-density, medium diameter, mean particle diameter and particle shape, are most closely related. Here, porosity has a stronger linear relation with dry-density, but a weaker linear relation with the mean particle diameter or the medium diameter. This paper shows that there is a close relation between acoustic velocity and porosity/grain medium diameter in one-parameter and two-parameter experiential formulas in sediment acoustic velocity and physical parameters. When determining particle piling structure, particle shape and grain size, we can calculate sedimentary theoretical porosity in order to judge sediment acoustic parameters and acoustic attenuation coefficient.
