Determination of Soil Permeability Using an Acoustic Technique
A new method for estimating the permeability of soils using an acoustic technique is proposed in this paper. Biot's coupled theory mixtures for elastic wave propagation is used. According to Biot, the permeability of saturated soils is related to the characteristic frequency of elastic waves. The characteristic frequency is determined from attenuation vs. frequency curve obtained by an acoustic sweep test in the field. This study presents the testing procedure for measuring the characteristic frequency of soils, the estimation of the permeability from the characteristic frequency and the comparison of the acoustic soil permeability with the in situ permeability test results. The measured permeability of soils using the acoustic technique was comparable to but generally higher than that obtained from in situ permeability test.
