EFFECTS OF VIBRATION ON BUCKLING OF SLENDER PILES, WITH CLOSURE

THE BUCKLING BEHAVIOR OF A SLENDER PILE IN SOFT CLAY HAS BEEN EXAMINED IN A LABORATORY SITUATION IN WHICH VIBRATIONS WERE TRANSMITTED THROUGH THE SOIL. THE LOAD-ROTATION BEHAVIOR WAS STUDIED FOR A STATIC ECCENTRIC LOAD. COMPARATIVE TESTS WERE CARRIED OUT WITH NO VIBRATION, VERTICAL VIBRATION AND HORIZONTAL VIBRATION. FOR SMALL SEVERITIES OF VIBRATION (PEAK PARTICLE VELOCITIES LESS THAN ABOUT 0.4 IN./SEC) IT WAS FOUND THAT THE LOAD CARRYING CAPACITY OF THE PILE WAS NOT SIGNIFICANTLY REDUCED. FOR LARGER VIBRATION SEVERITIES SOME REDUCTION IN THE LOAD CARRYING CAPACITY WAS FOUND. FROM A CONSIDERATION OF A POSSIBLE SCALING LAW FROM MODEL TO PROTOTYPE THESE FINDINGS WERE CONSIDERED TO BE AS VALID IN THE PROTOTYPE SITUATION AS IN THE LABORATORY SITUATION. FIELD VIBRATIONS FROM TRAFFIC WERE FOUND TO BE OF NEGLIGIBLE SEVERITY FROM A PILE BUCKLING POINT OF VIEW. FIELD VIBRATIONS FROM PILE DRIVING WERE MUCH MORE SEVERE BUT VIBRATIONS WERE FOUND TO DECAY RAPIDLY WITH INCREASING DISTANCE FROM THE SOURCE. /AUTHOR/
