ON THE BEARING CAPACITY OF DRIVEN PILES

THESE REPRINTS AND PRELIMINARY REPORTS COVER THE FOLLOWING SUBJECTS: 1. THE METHODS, WHICH ARE USED AT PRESENT (1970) IN SWEDEN, TO EVALUATE THE BEARING CAPACITY OF END-BEARING PRECAST CONCRETE PILES AND TO DETERMINE THE SOIL CONDITIONS AT A GIVEN SITE, ARE REVIEWED. 2. BEHAVIOUR OF PILES E.G. PERFORMANCE, INSTRUMENTATION AND INTERPRETATION OF LOAD TESTS ON PILES. DISTURBAMCE CAUSED BY THE DRIVING OF PILES. INFLUENCE OF PILE DRIVING ON SOIL COMPACTION, SOIL MOVEMENT AND BEARING CAPACITY OF ADJACENT PILES. EXPERIENCE WITH STEEL PILES IN SWEDEN. SWEDISH PILE SPLICING SYSTEMS. STRESSES IN STEEL PILES DURING THE DRIVING WITH AIR HAMMER. 3. AN EXPERIMENTAL STUDY IS PRESENTED ON THE POINT BEARING CAPACITY OF PILES DRIVEN INTO ROCK. THE TEST RESULTS ARE COMPARED WITH THE POINT BEARING CAPACITY CALCULATED BY THE COULOMB-MOHR AND THE GRIFFITH FAILURE THEORIES. 4. THE BEARING CAPACITY OF DRIVEN PRECAST CONCRETE AND TIMBER PILES HAS BEEN INVESTIGATED AT FOUR DIFFERENT SITES IN SWEDEN. THE MEASURED CRITICAL LOADS ARE COMPARED WITH CALCULATED VALUES. 5. THE EFFECTS OF REPETITIVE LOADS, DISTANCE FROM EXISTING OPEN AND CLOSED CRACKS AND THE SIZE OF THE LOADED AREA HAVE BEEN INVESTIGATED IN ORDER TO EVALUATE SOME OF THE FACTORS, WHICH AFFECT THE POINT BEARING CAPACITY OF END BEARING PILES DRIVEN TO ROCK. /TRRL/
