A MODEL TO DESCRIBE THE MECHANICAL PROPERTIES OF CLAYS

WHILE THE CONCEPT OF FRICTION AND THE ASSOCIATED PRINCIPLE OF EFFECTIVE STRESS GO A LONG WAY TOWARDS EXPLAINING THE SHEAR STRENGTH PROPERTIES OF CLAYS, SHORTCOMINGS BECOME EVIDENT WHEN EXTENSION IS MADE TO THE STRESS-VOLUME CHANGE PROPERTIES AND TO THE PHENOMENON OF SENSITIVITY. A MODEL IS PROPOSED IN WHICH STRENGTH IS ENVISAGED AS A FUNCTION OF THE STRENGTH OF BONDS BETWEEN CLAY PARTICLES MULTIPLIED BY THE NUMBER OF BONDS. A UNIFIED PICTURE WHICH EMBRACES THE MECHANICAL PROPERTIES OF CLAYS IS FOUND TO EMERGE FROM THIS CONCEPT AND THE INFLUENCE OF THE HITHERTO RATHER VAGUE CONCEPTS OF STRUCTURE AND STRESS HISTORY BEGINS TO BE SEEN. /RRL/A/
