HYSTERESIS PHENOMENON IN THE MOISTURE SUCTION RELATIONSHIP OF SOILS

MOISTURE-SUCTION CURVES WERE OBTAINED FOR THREE DIFFERENT SOILS (SANDY, ALLUVIAL, CLAYEY) AT FOUR DENSITIES. RESULTS SHOW THAT FOR A GIVEN SUCTION CLAYEY SOILS RETAIN MORE MOISTURE THAN SANDY SOILS AND THAT THE MAGNITUDE OF HYSTERESIS AT DIFFERENT VALUES OF SUCTION IS RELATED TO THE NATURE OF THE SOIL AND ITS STATE OF COMPACTION. CLAYEY SOILS SHOW A MORE PRONOUNCED HYSTERESIS EFFECT THAN SANDY SOILS. HYSTERESIS DECREASES WITH INCREASING DENSITY FOR SUCTION VALUES UP TO 5PF, BUT INCREASES AT HIGHER VALUES. /RRL/
