Title:

EFFECTIVE ANGLE OF FRICTION FOR A NORMALLY CONSOLIDATED CLAY

Accession Number:

Abstract:

IN ORDER TO DETERMINE THE LONG-TERM STABILITY OF A HOMOGENEOUS, NORMALLY CONSOLIDATED CLAY, ITS SHEAR STRENGTH UNDER DRAINED CONDITIONS WAS EVALUATED. THE EFFECTIVE ANGLE OF FRICTION WAS DETERMINED BY CONSOLIDATED, DRAINED SHEAR TESTS AND BY CONSOLIDATED UNDRAINED TRIAXIAL TESTS. THE RESULTS OBTAINED BY THESE TWO METHODS SHOWED A WIDE DIFFERENCE, NAMELY 22 DEGREES AND 26 DEGREES RESPECTIVELY. TWO METHODS WERE USED FOR CORRECTION OF THE TRIAXIAL TEST RESULTS WITH REGARD TO THE STRESS HISTORY OF THE TEST. BOTH THESE METHODS ARE BASED ON THE 'TRUE' ANGLE OF INTERNAL FRICTION, WHICH WAS DETERMINED BY A SERIES OF DRAINED SHEAR TESTS. WITH THE 15 DEGREES 'TRUE' ANGLE OF FRICTION THUS OBTAINED, THE TRIAXIAL TEST RESULTS WERE CORRECTED FROM 26 DEGREES TO 22 DEGREES, I.E. THE SAME VALUE AS THAT OBTAINED IN THE DIRECT SHEAR TEST. /RRL/A/
