DYNAMIC STUDIES ON THE BEARING CAPACITY OF PILES (VOL. 1 & VOL. 2)

VOL. 1 OF THIS TWO VOLUME SET DESCRIBES A SIMPLIFIED THEORY, BASED ON AN ASSUMED RIGID PILE AND THE UTILIZATION OF MEASUREMENTS TAKEN WHILE DRIVING A PILE, TO PREDICT THE ULTIMATE BEARING CAPACITY OF THE PILE. THE NECESSARY INSTRUMENTATION AND INSTRUMENT PROBLEMS ARE DISCUSSED AND THE FIELD TEST RESULTS FROM BOTH MODEL AND FULL SCALE PILES ARE EXAMINED. STRAIN AND ACCELEROMETER GAGES MOUNTED ON PILES WERE USED TO PREDICT THE BEARING CAPACITIES OF APPROXIMATELY 13 PILES AND THE RESULTS WERE COMPARED TO THE STANDARD MAINTAINED LOAD (ML) AND CONSTANT RATE OF PENETRATION (CRP) BEARING TESTS. RESULTS SHOW THAT ML AND CRP AGREE WITH ONE ANOTHER BUT THE DYNAMIC MEASUREMENTS OFTEN VARY GREATLY FROM THEM. THE USE OF THE CRP IS RECOMMENDED OVER THE ML TEST. VOL. 2 PRESENTS THE RESULTS OF A LITERATURE SEARCH AND THE DERIVATIONS OF SOME THEORETICAL MODELS FOR DESCRIBING PILE BEHAVIOR. THE COMMON FIVE TYPES OF GENERAL DRIVING FORMULAS ALONG WITH WAVE THEORY ARE BRIEFLY DESCRIBED. A COMPUTER NUMERICAL ANALYSIS TYPE OF SOLUTION BY SMITH IS USED TO DEVELOP ACCELERATION AND FORCE CURVES WHICH ARE MATCHED TO THE EXPERIMENTALLY DERIVED CURVES. THE COMPARISONS SHOW THAT MATHEMATICAL MODELS CAN BE USED TO SIMULATE PILE ACTION. THE BASIC EQUATION OF MOTION IS USED TO ANALYZE TWO THEORETICAL MODELS AND THE EXACT SOLUTIONS ARE OBTAINED FOR VARIOUS HYPOTHETICAL DRIVING FORCES. /BPR/
