The calculation of compressive bearing capacity of single filling pile is an important part of high-piled wharf and highway bridge design.With the trend of domestic engineering enterprises expanding overseas markets,the engineers are required to master and exercise design codes of different countries in a short time.By comparing Chinese Design Code for Wharf Structures,Design Code for Ground Base and Foundation of Highway Bridges and Culverts,and American AASHTO LRFD Bridge Design Specifications,we obtain the differences and similarities in side resistance and end resistance calculation details and reserve of safety factor.Based on the local drilling geological data of practical engineering,we compare the vertical compressive bearing capacity of single filling pile corresponding to the three codes,and evaluate the advantages and disadvantages of each code.The results show that the two Chinese codes are relatively simple but limited when encountering special soil.The American code has a clear concept and a wider scope of application,but the calculation process is relatively complex.
