Studies of Sediment Shear Waves, Acoustical Impedance, and Engineering Properties

Abstract

Compressional wave speed and attenuation have been measured in situ with the ARL/UT compressional wave profilometer. As an extension of this work, studies have been made of the feasibility of measuring shear wave speed and attenuation, as well as sediment bulk density in situ, using similar techniques. Various transducer configurations have been constructed and tested. Preliminary data have been measured using some of the transducers. Concurrent measurements of engineering properties enable comparisons to be made with acoustic properties. Instruments have been constructed to measure several sediment engineering parameters including Atterberg limits and vane shear strength.
