Measurement of Compressional Wave Parameters in Saturated Sands.

Abstract : The focus of this research was to improve the accuracy ot velocity and attenuation measurements so that a definitive test of the Biot-Stoll theory could be made. The major accomplishments during this period were refining the design of transducers, improving the procedures for making accurate laboratory measurements of the velocity and attenuation of shear and compressional waves in saturated sands, and locating the sources of experimental error. Preliminary measurements of compressional wave parameters were also made as the first step in testing the Biot-Stoll theory.
