EVALUATION OF PRESSUREMETER TESTS IN GRANULAR SOILS

IN THE METHODS OF INTERPRETATION OF PRESSUREMETER TESTS PROPOSED UNTIL NOW IT IS ASSUMED THAT THE VOLUME CHANGE OF THE SOIL DURING THE TEST IS ZERO. HOWEVER, WHEN A PRESSUREMETER TEST IS CARRIED OUT IN A GRANULAR SOIL UNDER DRAINED CONDITIONS, IT IS SHOWN IN THIS PAPER THAT THIS ASSUMPTION MAY RESULT IN OBTAINING AN INCORRECT SHAPE AND POSITION OF THE FAILURE ENVELOPE OF THE SOIL. A NEW METHOD OF INTERPRETATION IS PROPOSED WHICH TAKES INTO ACCOUNT THE VOLUME CHANGE OF THE SOIL DURING THE TEST AND MAKES IT POSSIBLE TO DETERMINE THE CORRECT FAILURE ENVELOPE FOR A GRANULAR SOIL UNDERGOING VOLUME CHANGES DUE TO COMPRESSION AND DILATANCY DURING THE TEST. /AUTHOR/
