In view of the different calculation methods of foundation bearing capacity of gravity wharf in the European standard system and the Chinese standard system,the design methods and calculation models of the two standard systems are compared and analyzed,and the foundation bearing capacity of a certain engineering case is calculated under the condition of drainage.The results show that there is a significant difference between them.The European code reflects the load uncertainty through the load partial factors.The Chinese code considers the relationship between vertical stress and vertical stress of foundation bearing capacity in the calculation of foundation bearing capacity，whose result is between the results of two combinations of Design Approach 1 in Eurocode.The two combinations shall be calculated when designing by UK National Annex for Eurocode and the calculation surface shall be chosen carefully for bearing capacity calculation of gravity wharf.
