FLOW AND FRACTURE PROPERTIES OF SEATTLE CLAYS

SOME OF THE MOST IMPORTANT SHEAR STRENGTH THEORIES OF SOILS THAT HAVE BEEN ADVANCED SINCE THE EARLY 1930'S ARE REVIEWED AND ANALYZED. THE SHEAR BEHAVIOR OF SEATTLE CLAYS CANNOT BE ANALYZED BY CONVENTIONAL STRENGTH THEORIES BECAUSE THE FAILURE STRESS DEPENDS ON TIME AND FAILURE STRAIN DEPENDS ON THE LEVEL OF STRESS. CONSEQUENTLY, A NEW SHEAR STRENGTH THEORY THAT CONSIDERS TIME EFFECTS AND DEFINES THE DESIGN STRENGTH OF A SOIL EXHIBITING TIME-DEPENDENT SHEAR BEHAVIOR AT THE CREEP LIMIT IS PROPOSED. FOR THE THREE TYPES OF SOILS TESTED, THE DESIGN SHEAR STRENGTH (CREEP LIMIT) OF SEATTLE CLAYS IS FOUND TO BE CLOSE TO 50 PERCENT OF THEIR SHORT-TERM SHEAR STRENGTH. A SERIES OF PARAMETERS ARE OFFERED FOR IDENTIFYING THE DEFORMATION AND FLOW PROPERTIES OF SEATTLE SOILS. /FHWA/
