摘　　要：对比分析了《建筑物防雷设计规范》(GB 50057)和《Protection Against Lightning》(IEC 62305)在建筑物防直击雷方面内容。从雷电流参数和防雷方法的角度介绍了两者的对应关系,对比了两者在防雷等级分类,风险评估,防雷装置措施等方面的异同。解释了GB 50057在建筑物防雷分类中所隐含的风险评估。对GB 50057是否适合"走出去"进行了讨论和分析,并提出了相关建议。Comparison and analysis are presented between Code for design protection of structures against lightning（ GB 50057） and IEC 62350 on structures direct lightning flash protection. A corresponding relationship between two standards is made by analyzing lightning current parameters and protection measures. Comparison is described from structures classifications,risk assessment,lightning protection system etc. It introduces the hidden risk analysis of structures classifications in GB 50057. This paper discusses the reason why GB 50057 can be used in the international engineering project,and some proposals are submitted.
