A MICROSTRUCTURAL VIEW OF THE MECHANICAL PROPERTIES OF SATURATED CLAY

THE MECHANICAL PROPERTIES OF CLAY-PLASTIC AND ELASTIC COMPRESSIBILITY, AND SHEARING OF NORMALLY AND HEAVILY OVERCONSOLIDATED CLAY ARE EXPLAINED BY MEANS OF A SIMPLE MICRO-STRUCTURAL MODEL. THIS IS SUGGESTED BY STRONG ANALOGIES BETWEEN THESE PROPERTIES AND THE EXPLANATION OF FRICTION BETWEEN DUCTILE METAL SURFACES IN TERMS OF PLASTIC BEHAVIOR OF JUNCTIONS FORMED BY CONTACT AT MICROSCOPIC ASPERITIES. THE MODEL AGREES WITH EXPERIMENTAL OBSERVATIONS, AND HELPS TO RESOLVE SOME PARADOXES INHERENT IN PREVIOUS INTERPRETATIONS OF THESE DATA. IT SUGGESTS EXPLANATIONS FOR THE RELATION BETWEEN THE PERMEABILITY OF A SOIL AND ITS VOIDS RATIO, AND FOR THE PHENOMENA OF SECONDARY CONSOLIDATION. THE MODEL ALSO PROVIDES CLUES ABOUT THE SIGNIFICANT FEATURES OF THE ORGANIZATION OF CLAY PARTICLES IN STRUCTURAL TERMS. /AUTHOR/
