摘要
重力式码头是一种常规码头结构形式,世界各国设计方法各有不同。综合对比分析中国港口工程规范和欧标(英标)对重力式码头结构设计的理论基础、计算参数、荷载组合、抗倾抗滑稳定验算和地基承载力验算等。结合算例,定量对比计算方法的差异,提出采用欧标进行重力式码头设计时须加以关注的方面。结果表明欧标(英标)计算方法总体偏于严格,尤其当采用土体强度考虑分项系数的验算方法时。
Gravity quay is a kind of conventional quay structure,and its design methods vary from country to country in the world.In this paper,according to Chinese port engineering codes and European(British)standards,we made a comprehensive comparative analysis of theoretical basis of design,calculation parameter,loading combination,the stability checking calculation of stability against sliding and overturning,and bearing capacity checking calculation of foundation for gravity quay structure design.Combined with the calculation example,we compare quantitatively the difference of calculation method,and put forward some aspects that should be paid attention to when using European standard to design gravityquay.The results show that the calculation method of the European(British)standard is generally more strict,especially when the checking method of soil strength partial factor is taken into account for the design method.
