Hubungan Daya Dukung Axial Fondasi Tiang Pancang Berdasarkan Data Spt, Kalendering Dan PDA
In the field conditions are often found a foundation design to be change due to differences in static and dynamic bearing capacity. In this research a study was conducted on the correlation between theoretical bearing capacity analysis with calendering and PDA as a dynamic test. Static bearing capacity is calculated based on N-SPT data with the Mayerhof method and the Luciano Decourt method. While dynamic tests based on calendering are calculated by the Hiley, ENR and WIKA methods, then also compared with the PDA test results. Static and dynamic testing points are close is in Abutment 1 with the dominant soil type is a sandy. The results of calculating the axial bearing capacity using SPT data with the Mayerhof and Luciano Decourt methods are more greater than the results of the calendering method calculation. Comparison between the dynamic bearing capacity of the calendering and PDA is close to several points. The Hiley method has the smallest value difference of 0.272 tons. At one of the calendering test points, the WIKA method also approaches the PDA results of 0.292 tons, while the ENR method does not have a value that is very close to the PDA test results. Overall, at five adjacent test points, the WIKA method is closer to PDA results. So that in this study the bearing capacity of the WIKA method and PDA test results become a reference in determining the axial bearing capacity of the pile foundation.
