DETERMINATION OF THE VERTICAL LOAD BEARING CAPACITY OF SOB (CAST IN SITU) PILES

EIN BEITRAG ZUR ERMITTLUNG DER VERTIKALEN TRAGFAEHIGKEIT VON SOB-PFAEHLEN

STIFF, CAST IN SITU (SOB) PILES ARE BEING USED INCREASINGLY IN PLACE OF TRADITIONAL FOUNDATIONS. GENERALLY THEY ARE EXCAVATED BY HYDRAULIC EXCAVATOR WITH THE AID OF SUSPENSIONS. IN ORDER TO DETERMINE THE VERTICAL LOAD BEARING CAPACITY OF PILES WITH RATIOS OF DEPTH TO DIAMETER 1 : 8, MODEL TESTS HAVE BEEN CARRIED OUT. THESE WERE DESIGNED MAINLY TO INVESTIGATE THE INFLUENCES UPON THE GEOMETRIC DIMENSIONS OF THE PILES, OF THE PARAMETERS OF A NON-COHESIVE SOIL AS WELL AS THE BEARING PRESSURE AND THE SKIN FRICTION. IN ADDITION TO THE GEOMETRIC PARAMETERS THE SOIL PROPERTIES WERE VARIED IN ORDER TO ENSURE THE GENERAL VALIDITY OF THE RESULTS. FOLLOWING THE SELECTION OF A RELATIVE SETTLEMENT IN RELATION TO THE DIAMETER AS A DEFINITIVE CRITERION FOR THE LIMITING LOAD BEARING CAPACITY IT WAS POSSIBLE TO DETERMINE THE RELATIONS BETWEEN THE SOIL PROPERTIES, THE PILE GEOMETRY AND THE LOAD BEARING CAPACITY OF THE PILES FROM THE TIME-LOAD-SETTLEMENT CURVES. THE COVERING ABSTRACT FOR THE CONFERENCE IS IRRD NO 306088.
