摘要
根据建筑物防雷理论和规范要求,结合广州国际金融中心(广州西塔)工程实例,详细介绍超高层建筑防雷设计方法,包括参考雷击风险评估报告确定防雷等级,以及防直击雷、防侧击雷、防雷击电磁脉冲的措施等,并提示超高层建筑防雷设计注意事项。近几年雷暴的考验,证明广州西塔防雷设计先进、合理、可靠。
Design methods of protection against lightning for super high-rise buildings are introduced in detail according to protection against lightning theories and specification clause for buildings in combination with practical engineering project of Guangzhou International Finance Center （ Guangzhou West Tower）. Protection against lightning class determined according to a lightning risk assessment report, and measures for protection against direct lightning, side lightning and protection against lightning electromagnetic impulse are also proposed, and matters in design of protection against lightning for super high-rise buildings are prompted. Proved by thunderstorms over the years, the design of protection against lightning for Guangzhou West Tower is advanced, reasonable and reliable.
