THE PROBLEM OF PILE GROUP-PILE CAP INTERACTION

AN ELASTIC ANALYSIS IS PRESENTED OF TWO PROBLEMS CONCERNING THE INTERACTIONS WITH THE SUPPORTING GROUND OF AN ARBITRARILY SPACED GROUP OF PILES, EMBEDDED IN A SMOOTH GROUND CONTACTING PILE CAP OF ANY SHAPE, NAMELY THE LOAD DISPLACEMENT BEHAVIOR OF THE SYSTEM AND THE LOAD DISTRIBUTION BETWEEN THE PILES IN THE GROUP AND THE CAP. THE PROBLEMS ARE FORMULATED AS AN INTEGRAL EQUATION DEVELOPED FROM MINDLIN'S ANALYSIS FOR A POINT LOAD EMBEDDED WITHIN A SEMI-INFINITE IDEAL ELASTIC HALF SPACE. THE EFFECT ON THE RESPONSE OF THE SYSTEM OF THE PILE LENGTH TO DIAMETER RATIO, PILE CAP SIZE AND THE COMPRESSIBILITY RATIO OF THE PILE AND SUPPORTING MEDIUM HAS BEEN INVESTIGATED AND SPECIFIC RESULTS ARE PRESENTED GRAPHICALLY FOR A SINGLE PILE WITH A SQUARE CAP AND TYPICAL PILE GROUPS IN SQUARE AND RECTANGULAR ARRAYS. /RRL/
