Under the promotion of the national “One Belt and One Road” initiative,the pretension prestressed high-strength concrete (PHC) pipe pile has been comprehensively applied in various overseas engineering projects. However,there are large differences between the specifications and design theories in foreign areas,which makes the mechanical properties of PHC piles based on Chinese standards are difficultly be adapted by the designers abroad.This paper compares the concrete structures and piles prescribed in the standards of China,America,British,Europe and Japan,especially the axial-bending capacities for PHC piles,which are mostly significant to the design.After comparisons,it is found that the simplified equations given by Chinese standards,at the expenses of some accuracy,can draw smooth curves for axial-bending capacities of PHC piles.However,due to the large differences of the definition of design axial capacities in different foreign standards,it is hard to give integrated and smooth curves.
