Comparative Analysis of Analytical Rational Method in Calculating Bearing Capacity of Pile Foundation Based on N-SPT Data Against Capwap Test Results Pda

Key Points

The Meyerhoff method provides the highest tip bearing capacity values in comparisons with CAPWAP results.
N-SPT data yields varying total bearing capacity ratios from 0.82 to 1.64, with Terzaghi & Peck showing the highest ratio.
Analytical methods like Nakazawa and Meyerhoff demonstrate significant differences in average comparison values against CAPWAP.
The closest values to 1 in total bearing capacity are found using Meyerhoff and Luciano Decourt & Quaresma methods.

Abstract

This research aims to analyze the comparative value of analytical rational methods in calculating the bearing capacity of pile foundations based on N-SPT data. The results of calculating the bearing capacity of pile foundations by analytical methods (Luciano Decourt Luciano Decourt (1982) Vesic (1977) and Tomlinson (1977); Reese O'neil (1999); Terzaghi 0.88; 1.14; 1.56; 1.57; 1.64 respectively. The comparison of the total bearing capacity of the analytical method to the CAPWAP analysis that is closest to 1 is the Meyerhoff (1956) and Luciano Decourt (1982) & Quaresma (1978) method. Therefore, the most effective analytical methods in calculating the total bearing capacity of piles are Meyerhoff (1956) and Luciano Decourt (1982) & Quaresma (1978) methods.
