Theory basic calculation of conventional driving formulae gave the underprediction except "the Engineering News Formula". "The Janbu's Formula" gave good estimation of the ultimate load of driven pile. The proposed constants were deduced from ultimate capacity of static load test. Then, the correlation between the ultimate capacity of static load test and the dynamic load test were also evaluated. The proposed constants can give a good estimation of ultimate static load after correction.
