dc.description.abstractA three-dimensional model for the study of surface wave speed measurements in simulated ocean bottom sediments has been constructed using a high-porosity kaolinite-water mixture in a rectangular tank in the laboratory. The propagation of surface waves , assumed to be Rayleigh waves , was studied over the 75 Hz to 300 Hz frequency range using a gated sine wave source and several geophone receivers. Shear wave speeds in the sediment are determined to be 23 m/sec. These measurements are qualitatively compared with measurements made by previous investigators in similar sediments using a torsionally oscillating rod viscoelastometer whose resonant characteristics are sensitive to loading by the sediment in which it is imbedded. Good correlation of results is found with the shear wave speeds calculated from the viscoelastometer data which are in the range of 20 to 30 m/sec.en_US
