FLOATING CAISSON FOUNDATIONS

Steel Piles with Attachments

DESIGNS ARE PRESENTED OF TWO FOUNDATIONS FOUNDED UPON A NEW FLOATING CAISSON TYPE FOUNDATION. THE STRUCTURES BUILT IN THIS WAY IN THE NEW YORK CITY AREA ARE PIER 57 AND THE NYACK-TARRYTOWN BRIDGE. ABOUT 85 PERCENT OF THE LOAD OF THE PIER AND 65 PERCENT OF THE LOAD OF THE BRIDGE ARE CARRIED BY BUOYANCY. GEOLOGIC PROFILES AND FLOATING CAISSON FOUNDATIONS STRUCTURES ARE PRESENTED. DETAILS OF THE ACTUAL CONSTRUCTION PROCESS ARE REVIEWED. THE FINISHED PIER CONSISTS OF A GROUND LEVEL PLUS TWO UPPER FLOORS. THE CONSTRUCTION OF A FLOATING PIER ELIMINATED THE NEED FOR LONG EXPENSIVE PILES FOR THE FINGER PORTION. THIS METHOD PRODUCED AN EFFICIENT, HIGH-CAPACITY, MODERN PIER CONSTRUCTED ON POOR FOUNDATION MATERIALS FOR ABOUT THE SAME AMOUNT OF MONEY AS WOULD BE REQUIRED FOR A SIMILAR PIER ON REASONABLY GOOD FOUNDATION MATERIALS. THE DESIGN HAS BEEN MADE OF SEVERAL PROJECTS ON WHICH IT WAS FOUND ECONOMICAL TO PUT ATTACHMENTS NEAR THE FOOT OF STEEL PILES IN ORDER TO INCREASE THEIR BEARING CAPACITY. THE DESIGN OF ATTACHMENTS FOR SUCH PROJECTS IS DESCRIBED. A VERY LARGE SAVING IN COST WAS PROVIDED BY DESIGNING THE PILES TO DEVELOP THEIR BEARING CAPACITY IN THE STRATIFIED SILT AND SAND LAYER OVERLYING THE DEEP CLAY DEPOSIT.
