Effects of soil compressibility and damping on wave-induced seafloor movements are studied. A theoretical solution for coupled ocean wave-seafloor interaction is developed based on an continuum mechanics. The wave-induced stresses and displacements in the soil can be computed using the theoretical solution. The attenuation of the ocean wave height also can be determined from the solution. The solution was verified by comparing the results of computations to other researchers' solutions, and parametric studies were performed to examine the effects of various soil properties on the soil responses. Gaseous soil specimens were prepared in the laboratory and experiments were performed to determine the dynamic properties of the compressible gaseous soil in both shear and compression. Resonant column tests were used to determine the dynamic properties in shear, cyclic compression tests were developed, and used to measure the dynamic properties in compression. The measured soil properties were represented by mathematical models and employed in computations with the theoretical solution, which was extended to include nonlinear soil behavior and a multi-layered soil system. Results of the computations indicated that the compressibility of the soil could have significant effects on both the horizontal and vertical displacements of the soil responses and the attenuation of the wave height were dependent on the thickness of the soil layer. Assumption of an incompressible soil could lead to very different results especially in the case of thin soil layer.Subjects--Topical Terms:
