THE ROLE OF POROSIMETRY IN GEOMECHANICS

THE MOST FUNDAMENTAL PARAMETERS USED TO CHARACTERIZE SOILS AND ROCKS ARE THOSE THAT ARE FUNCTIONS OF THE POROSITY. TO DATE ENGINEERS HAVE, OF NECESSITY, USED GROSS POROSITY AS THE ONLY PRACTICAL MEASURE. HOWEVER, THE APPLICATION OF THE TECHNIQUES OF POROSIMETRY ENABLE THE COMPLETE DISTRIBUTIONS OF PORE SIZES AND PORE VOLUMES TO BE DETERMINED. THE THEORY AND TECHNIQUES OF MERCURY INTRUSION POROSIMETRY ARE DESCRIBED AND THE ERRORS AND LIMITATIONS OF THE METHOD ARE DISCUSSED. IT IS THEN SHOWN THAT, BY USING POROSIMETRY, INFORMATION CAN BE OBTAINED ON SOIL PROPERTIES WHICH HAS NOT HITERTO BEEN AVAILABLE. MOREOVER, IT IS POSSIBLE TO DEFINE SEVERAL NEW PARAMETERS WHICH CAN USEFULLY SUPPLEMENT CONVENTIONAL MEASUREMENTS BASED ON GROSS POROSITY. FINALLY, THE ROLE OF POROSIMETRY TO INVESTIGATING A WELL KNOWN ENGINEERING SYSTEM IS DISCUSSED AND TYPICAL EXPERIMENTAL DATA ARE PRESENTED. /AUTHOR/
