DISPLACEMENTS IN A SOIL MASS DUE TO PILE GROUPS

THE SETTLEMENT OF COMPRESSIBLE SOIL LAYERS UNDERLYING PILES AND THE SETTLEMENT OF THE GROUND SURFACE SOME DISTANCE AWAY FROM PILES, E.G. THE ADDITIONAL SETTLEMENT OF AN EXISTING BUILDING DUE TO A NEW STRUCTURE, ARE EXAMINED. NUMERICAL SOLUTIONS ARE OBTAINED FOR THE VERTICAL DISPLACEMENT WITHIN A SOIL MASS DUE TO A SINGLE LOADED PILE; USING THESE SOLUTIONS, THE AUTHORS DESCRIBE METHODS FOR CALCULATING THE SURFACE DISPLACEMENT PROFILE AROUND A PILE GROUP AND THE SETTLEMENT OF SOIL LAYERS BENEATH A PILE ON A PILE GROUP. IN OBTAINING THE SOLUTIONS FOR THE DISPLACEMENTS DUE TO A SINGLE PILE, IT IS ASSUMED THAT NO LOCAL FIELD OCCURS BETWEEN THE PILE AND THE SOIL, AND THAT CONDITIONS WITHIN THE SOIL REMAIN PURELY ELASTIC. IN CONSIDERING THE SETTLEMENT OF PILE GROUPS, THE GROUPS ARE ASSUMED TO BE FREE-STANDING WITH NO CONTACT BETWEEN THE PILE CAP AND THE SOIL. ANALYSIS HAS SHOWN THAT, EVEN IF THE PILE CAP IS, IN FACT, IN CONTACT WITH THE SOIL, IT HAS LITTLE INFLUENCE ON THE SETTLEMENT OF THE GROUP, PROVIDED THE PILE SPACING IS RELATIVELY CLOSE AND ELASTIC CONDITIONS PREVAIL WITHIN THE SOIL. /TRRL/
