ELASTIC MODULI OF SOILS CONTAINING LARGE GAS BUBBLES

A conceptual model for soils containing large gas bubbles is analyzed to provide theoretical expressions for the drained and undrained elastic moduli. Experimental values of the undrained moduli, meausured in triaxial tests at large strains, show little agreement with the theoretical predictions. This lack of agreement is probably caused by concentrated local plastic straining, which is likely to occur in soils containing gas bubbles at all but the smallest strains. The undrained behavior at very small strains, as represented by acoustic measurements of the compression wave velocity, shows much better agreement with the theoretcal predictions. Improved understanding of small strain behavior of soils containing large gas bubbles could be of considerable benefit to the offshore industry, for predicting the deformation of foundations constructed on gas-bearing sediments.
