TESTS OF LATERALLY LOADED PILES

THE RESULTS OF 6 LATERAL LOADING TESTS ON BORED CAST-IN-SITU CONCRETE PILES (48 AND 66 CM DIA) ARE ANALYSED. FOUR PILES WERE LOADED BY HORIZONTAL LOAD (25 AND 50 T) ONLY. TWO WERE ALSO SUBJECTED TO CONSTANT VERTICAL LOAD DURING THE TESTS. THE TEST RESULTS WERE CONFRONTED WITH THEORETICAL CALACULATIONS ACCORDING TO BROMS (1965). THE QUANTITIES COMPUTED WERE THE LIMIT HORIZONTAL LOAD AND THE DISPLACEMENT USING THE COEFFICIENT OF HORIZONTAL SUBGRADE REACTION DEDUCED FROM STANDARD PLATE LOADING TESTS. FOR DISPLACEMENT CALCULATION TO AGREE WITH THE TEST RESULTS THE VARIABILITY OF THE COEFFICIENT OF SUBGRADE REACTION HAD TO BE ASSUMED. THIS IS EXPLAINED BY DIFFERENT DEGREES OF DISTURBANCE OF THE FOUNDATION SOIL DURING THE BORING OF THE INDIVIDUAL PILES. THE CALCULATION OF THE PILE BEARING CAPACITIES WAS RATHER CONSERVATIVE. THE VERTICAL LOAD TO WHICH SOME OF THE PILES WERE SIMULTANEOUSLY SUBJECTED, AFFECTED THE RESULTS IN NO WAY. SEE ALSO IRRD ABSTRACT NO. 100334.
