A comparative study is conducted on the calculation methods of different domestic and foreign standards for the structure of caisson gravity wharfs using different specifications.The limit state design method based on probability theory is adopted to calculate the structure of a newly built caisson gravity wharf.The focus is on comparing the differences in load sub coefficients and working condition combinations between Chinese and foreign standards.The differences in anti tilting and anti sliding stability of the caisson gravity wharf structure under different working condition combinations are analyzed.When conducting anti slip stability verification,the design of the American and European standard combination M2 is relatively safe,with the Chinese standard being between the European standard combination M2 and M1,and the safety factor in the Japanese standard being relatively small.In the calculation of anti tilt stability,the European standard is relatively safer compared to the Chinese standard,and the comprehensive safety factor of the American and Japanese standards is higher than that of the European and Chinese standards.This comparative study can provide relevant reference and guidance for the design of caisson gravity wharfs both domestically and internationally.
