中英港口水工建筑物规范中荷载组合规则的要点分析

Key points of load combination for maritime works in Chinese and British codes

比较中英港口水工建筑物规范的荷载组合规则的一致性与差异性,中国各设计规范中荷载组合规则存在局部不一致,而英国标准BS 6349与欧洲统一设计标准保持较好的一致性。结合某码头工程实例,按中国标准荷载组合规则设计比按英国标准设计的灌注桩的主筋用钢量高约20%。

The consistency and difference of load combinations for the marine structures in Chinese and British codes are studied in detail. It is shown that the slightly differences of load combination among the Chinese codes exist, while that of BS 6349 is inherently consistent with Eurocodes well.Finally, a real port project is provided that the amount of main rebar for bored pile under the load combinations in the Chinese code is 20% higher than British standard.
