摘　　要：根据GB 50057—2010《建筑物防雷设计规范》,分析了在建筑物防雷设计时大量使用辅助接地体和安装Ⅱ级试验电涌保护器的问题。通过对实际案例的接地设计计算和形成电涌的损害源分析,提出不同环境的建筑物要考虑高低压线路的不同敷设方式,在接地和防电涌方面须采用不同的设计方案,以节约建设成本。According to national standard GB 50057-2010,this paper introduced the two problems of lightning protection design in building, including the extensive use of attxiliary grounding body and the installed II level experimental surge protective device（SPD）. Through the grounding design calculation and the analysis of surge damage source in the actural project,the high voltage and low voltage circuit laying modes are eonsidered in different buihlings, so the different design schemes of grounding and surge protection are adopted, prevent the monotony of the modular design,which can save the construction cost.
