FAILURE OF PILE-SUPPORTED STRUCTURES CAUSED BY SETTLEMENTS

THIS ARTICLE ANALYZES THE MOMENT EXISTING IN SLOPED PILES DRIVEN THROUGH A LAYER OF CLAY WHERE SETTLEMENT OCCURS IN THE SOIL SURROUNDING THE PILE. THE ARTICLE IS BASED ON THE HYPOTHESIS THAT THE LATERAL LOAD ON THE PILES IS PROPORTIONATE TO THE RELATIVE SOIL DISPLACED BY THE PILES. THE HORIZONTAL COEFFICIENT OF SUBGRADE REACTION KH WAS TAKEN TO BE 10 CU/D, CU REPRESENTING THE UNDRAINED SHEARING RESISTANCE OF THE SOIL, AND D REPRESENTING THE DIAMETER OR SIDE OF THE PILE. THE SETTLEMENT LEVEL OCCURRING DURING FLOWING OF THE REINFORCEMENT IN THE PILES WAS FOUND TO BE SMALL WHEN THE PILES WERE RESTRAINED AND THE SOIL AND SOIL SURFACE HAD A DRY CRUST WITH A HIGH LEVEL OF SHEARING RESISTANCE. THE COVERING ABSTRACT FOR THE CONFERENCE IS IRRD NO 306088.
