APPARATUS FOR MEASURING SUCTION UNDER EXTERNAL LOADS

AN APPARATUS WHICH MEASURES NEGATIVE PORE PRESSURES DURING DRYING AND WETTING PROCESSES UNDER EXTERNAL LOADS IS DESCRIBED, AND TEST RESULTS ON A HEAVY CLAY AND A SAND ARE PRESENTED. THE PRESENT APPARATUS CONTINUOUSLY MEASURES SUCTIONS UNDER EXTERNAL LOADS /NEGATIVE PORE PRESSURES/ IN A SINGLE OPERATION AND DETERMINES MOISTURE CONTENTS WITHOUT REMOVING THE SOIL SAMPLE FROM THE SUCTION PLATE, THUS AVOIDING INTERFERENCE IN THE CONTACT BETWEEN THE SOIL AND THE PLATE. FOR THE RANGE OF MEASURABLE SUCTION THE APPARATUS PRODUCED A COMPRESSIBILITY FACTOR, EQUAL TO UNITY FOR THE HEAVY CLAY AND EQUAL TO APPROXIMATELY ZERO FOR THE SAND, WHICH AGREES WITH THE BRITISH ROAD RESEARCH LABORATORY /RRL/ WORK. /AUTHOR/
