Bearing capacity analysis of pile foundation based on soil investigation compared to Pile Driving Analyzer (PDA)

Abstract

The analysis of the dynamic bearing capacity of pile foundations is an important aspect of understanding the interaction between structures and soil. This study aims to determine the pile bearing capacity based on data from the Standard Penetration Test (SPT) and Cone Penetration Test (CPT), which were verified using the results from the Pile Driving Analyzer (PDA) test. The static analysis methods applied in this study include those developed by Meyerhof (1976), Vesic (1977), de Ruiter and Beringen (1979), and Penpile (1978). The results of the static analysis of pile bearing capacity are consistent with the PDA test results. These findings demonstrate that the PDA test is a valid and reliable reference for evaluating pile bearing capacity in the field. The analysis results using the de Ruiter and Beringen method with CPT data show a very close correlation with the pile capacity obtained from the PDA test. Meanwhile, the analysis results using the Vesic and Meyerhof methods with SPT data are slightly closer to the PDA test results. These methods are consired appropriate in pile bearing capacity analysis, as they consistently produce capacity values that fall within the range of those obtained from the PDA test.
