港区铺面设计中的集装箱角荷载

Container corner load in port pavement design

针对我国港区铺面中现行的集装箱角荷载设计方法的合理性问题,通过统计分析当前我国7个港口的集装箱质量分布规律,指出现行《港口工程荷载规范》与《港口道路与堆场设计规范》中关于集装箱角设计荷载规定的不合理之处:前者采用基于英国港口集装箱质量分布数据的折减系数法不符合我国情况,严重偏小;后者不能体现不同重要程度港口的设计需求差异性。进而,提出铺面结构设计时确定集装箱角荷载的建议。成果完善和改进了我国集装箱角荷载的设计方法,对港区铺面的建设和使用具有重要的价值和意义。

Aiming at the problem of the rationality of the current design method of container corner load in the pavement of China’s port,we carry out the statistical analysis of the distribution law of container weight in seven important ports in China at present,and point out the deficiencies of container corner design load in the current The Load Code for Harbor Engineering and The Design Code of Road and Storage Yard for Port Area.The former adopts the reduction coefficient method based on the container redistribution data of British ports,which is not in line with China’s situation and seriously small.The latter cannot reflect the difference of port design requirements with different degrees of importance.Furthermore,we propose some suggestions on determining the corner load of container in pavement structure design.The results improve the design method of container corner design load in China,which has important value and significance for the construction and use of port pavement.
