摘要 针对欧洲规范体系和中国规范体系中重力式码头地基承载力计算方法不同的问题,通过对两套规范体系的设计方法和计算模型对比和分析,并结合某工程实例计算排水情况下的地基承载力,结果表明二者存在明显差异。欧洲规范通过荷载分项系数反映了荷载的不确定性;中国规范则在地基承载力计算时考虑竖向应力和地基承载力竖向应力的关系,计算结果介于欧标设计方法 1两种组合的结果之间。用欧洲规范英国国家附录进行设计时须验算两种组合方法,计算重力式码头地基承载力时还应注意计算面的选取。 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.
