THE SETTLEMENT OF UNDER-REAMED AND STEP-TAPER PILES

A THEORETICAL ANALYSIS, BASED ON ELASTIC THEORY, IS MADE OF THE SETTLEMENT BEHAVIOUR OF INCOMPRESSIBLE UNDER-REAMED AND STEP-TAPERED PILES WITHIN A SEMI-INFINITE MASS. IT IS SHOWN THAT AN UNDER-REAMED PILE SETTLES LESS THAN A UNIFORM PILE OF EQUAL SHAFT DIAMETER, THE MAGNITUDE OF THIS SETTLEMENT REDUCTION BEING DETERMINED PRIMARILY BY THE DIAMETER OF THE ENLARGED BULBS AND BY THE TOTAL EFFECTIVE LENGTH OF THESE BULBS. STEP-TATER PILES ARE FOUND TO SETTLE MORE THAN A UNIFORM PILE OF EQUAL BUTT DIAMETER, THIS INCREASE IN SETTLEMENT BEING DEPENDENT ONLY ON THE RATIO OF THE PILE SETTLES LESS THAN A UNIFORM PILE WHICH IN TURN SETTLES LESS THAN A STEP-TAPER PILE. /AUTHOR/
