THE ONE-DIMENSIONAL THEORY OF TERZAGHI CAN BE EXTENDED TO THREE DIMENSIONS IF THE INITIAL DISTRIBUTION OF PORE WATER PRESSURES IS KNOWN. THIS THEORY IS SIMILAR TO THAT OF BIOT WITH THE EXCEPTION THAT THE NORMAL STRAINS ARE NOT DEFINED DURING CONSOLIDATION OTHER THAN BY THE GENERAL CONDITIONS OF COMPATIBILITY OF STRAIN. ONLY THE VOLUMETRIC STRAIN IS PRESCRIBED. EXPERIMENTAL EVIDENCE IS PRESENTED IN FAVOR OF THE FORMER APPROACH, AND A COMPLETE SOLUTION, INCLUDING STABILITY ANALYSIS, IS MADE OF A CONSOLIDATING RIGID CIRCULAR FOOTING USING THE GENERALIZED TERZAGHI THEORY. A STUDY IS ALSO MADE OF SECONDARY COMPRESSION WHICH IS SHOWN TO BE DUE TO VARIATIONS IN THE COEFFICIENT OF PERMEABILITY. THE BULK MODULUS OR COEFFICIENT OF COMPRESSION IS SHOWN TO BE VERY NEARLY CONSTANT, IN SPITE OF VARIATION OF THE POISSON RATIO DURING CONSOLIDATION, AND IS PROPORTIONAL TO THE AVERAGE PERMEABILITY. /AUTHOR/
