INFLUENCE OF THE DIRECTION OF CLAY PARTICLES ON THE SHEARING STRENGTH OF CLAY /IN POLISH/

THE ORIENTATION OF PARTICLES IN CLAYEY SEDIMENTS MARKEDLY INFLUENCES THE STRESS DISTRIBUTION AND SHEARING STRENGTH OF THE SOIL MASS. DETAILS ARE GIVEN OF A SERIES OF TESTS ON KAOLIN. PARTICLE ORIENTATION WAS DETERMINED BY X-RAY DIFFRACTION, AND THE SHEARING STRENGTH WAS STUDIED IN UNDRAINED TRIAXIAL TESTS DURING WHICH THE PORE PRESSURE WAS MEASURED. THE AXIS OF THE CLAY SAMPLES WAS AT ANGLES OF 45 AND 90 DEGREES TO THE PARTICLES. FOR AN IDENTICAL MOISTURE CONTENT, THE SAMPLES WHOSE AXIS WAS PARALLEL TO THE PARTICLES SHOWED A MAXIMUM DEVIATOR VALUE. THE SAME SAMPLES WERE CUT VERTICALLY, HORIZONTALLY, AND OBLIQUELY AND SUBJECTED TO VANE TESTS. SHEARING PARALLEL TO THE PARTICLES RESULTED IN MINIMUM STRENGTH; MAXIMUM STRENGTH WAS OBSERVED IN SAMPLES INCLINED AT 45 DEGREES. /LCPC/RRL/
