SHEAR STRENGTH PARAMETERS AND MICROSTRUCTURE CHARACTERISTICS OF A QUICK CLAY OF EXTREMELY HIGH WATER CONTENT

A CLAY OF EXTREMELY HIGH SENSITIVITY AND EXTREMELY HIGH WATER CONTENT WAS INVESTIGATED WITH RESPECT TO THE STRENGTH CHARACTERISTICS. IN ADDITION, THE CONSTITUENTS AND THE MICROSTRUCTURE OF THE CLAY WERE EXAMINED. MICROSTRUCTURAL INVESTIGATIONS BASED ON ELECTRON MICROSCOPY INDICATE THE CLAY MICROSTRUCTURE TO BE CHARACTERIZED BY AN EXTREMELY OPEN THREE-DIMENSIONAL NETWORK OF PARTICLES AND PARTICLE GROUPS. THE SHEAR STRENGTH CHARACTERISTICS WERE DETERMINED BY TRIAXIAL TESTS, DIRECT SHEAR AND UNCONFINED COMPRESSION TESTS. THE DIFFERENT TYPES OF TESTS GAVE DIFFERENT VALUES OF CERTAIN STRENGTH PARAMETERS. THE DIFFERENCES ARE SAID TO BE DUE TO ANISOTROPIC FACTORS OWING TO THE DIFFERENT CONSOLIDATION AND STRESS CONDITIONS PREVAILING IN THE TRIAXIAL AND THE DIRECT SHEAR TESTS. THE MICROSTRUCTURAL CONDITIONS INVOLVED ARE ALSO DISCUSSED. /A/RRL/
