In marine engineering，steel pipe pile is the most widely used pile type，and the calculation of the uplift bearing capacity of steel pipe pile is an important content for pile foundation design. The API RP 2A-WSD code and European code EN 1997-1 are the main references for the design of pile capacity in foreign engineering. In this paper，the similarities and differences between these codes，the technical code for building pile foundation and the design codes for wharf structure are systematically described，and the uplift bearing capacity of steel pipe pile is calculated combined with practical engineering. Compared with the calculation results of various methods，it is found that：1） In the stratum dominated by cohesive soil，the deviation between the calculated pile side resistance value and the measured value in the technical code for building pile foundation is the smallest.2） In the stratum dominated by cohesive soil and sandy soil，the calculated results by the technical code for building pile foundations and API code have the smallest deviation from the measured result. 3） The design value of uplift bearing capacity calculated by EN code is the smallest. 4） The shaft resistance values of soft rock can be obtained from the technical code for building pile foundations or the method described by Michael Tomlinson.
