摘　　要：结合IEC相关防雷标准,分析探讨大底盘建筑群接地系统特点,指出:大底盘是一等电位面,其上多栋建筑的结构基础不存在独立的防雷地;大底盘建筑群,无论俯瞰有多少栋,就防雷而言,就是基于同"一个"完整"接地系统"的连体建筑物。由此得出结论:在大底盘建筑群内配置"协调配合的SPD系统",其原则和方法与单一建筑物完全一致;该结论源于IEC标准,而且在GB 50057-2010《建筑物防雷设计规范》也有设计依据。Combined with the IEC standard of lightning protection, the characteristics of earthing system of large-chassis buildings are analyzed and discussed, and points out that the large-chassis is an equipotential plane, on which the structure foundation of many buildings have no independent lightning ground, regardless of the number of buildings when viewed from above, is a conjoined building based on the ＂same＂ complete ＂earthing system＂. It is concluded that the principle and method for configuring ＂ coordinated SPD system＂ in large-chassis buildings are completely consistent with those of single building; and this conclusion is supported by the design basis in IEC standard and GB 50057- 2010 Code for Design Protection of Structures against Lightning.
