The calculation of the wave uplift force is very important for the design of the high-pile wharf structure,but the calculation methods are different based on different codes.International standards such as European and American standards are generally recognized internationally,or local standards are adopted. In order for better promoting the Chinese codes in international projects,comparative analysis of several codes is usually required.According to the Chinese industry code and manuals,combined with specific engineering examples,this paper compares the British standards,US standards,Japanese standards,ISO standards,PIANC standards and other commonly used foreign specifications.Furthermore,combined with several different wave period conditions commonly used in engineering,we analysed the relationship between the total wave uplift force and the ratio of the height of the bottom of the structure above the static water surface to the design wave height;for the condition of medium water depth and deep water depth,we analysed the differences and characteristics of wave uplift force in different periods of different water depths base on different calculation method,and gives suggestions for the application of overseas.
