LONGITUDINAL VARIATIONS OF SOIL DISTURBANCE WITHIN TUBE SAMPLES

IT IS KNOWN THAT SOME OF THE VARIABILITY IN RESULTS OF TRIAXIAL COMPRESSION TESTS ON "UNDISTURBED" SOIL SAMPLES CAN BE ATTRIBUTED TO THE POSITION IN THE CORE FROM WHICH THE TEST SPECIMEN IS CUT. FROM THE RESULTS OF A SPECIFIC SET OF EXPERIMENTAL SAMPLINGS IT WAS FOUND THAT (1) IN ALL CASES THE SECANT MODULUS WAS HIGHER IN THE LOWER PART OF A TUBE SAMPLE THAN IN THE UPPER PART; (2) IN ALL BUT TWO CASES, A SIMILAR CONDITION EXISTED FOR THE PEAK STRENGTH. THESE EFFECTS EXCEED THOSE THAT CAN BE ATTRIBUTED TO VARIATIONS OF OF DEPTH OR WATER CONTENT. /RRL/A/
