摘　　要：针对多避雷针系统接闪器布设过于依赖工程经验的问题,基于最小成本原则,以多接闪器的高度和安装位置为优化变量,建立了多避雷针系统接闪器布设的优化模型,提出了基于遗传算法的多避雷针系统接闪器布设优化方法,通过典型设计案例对所提优化设计方法的有效性进行了验证。结果表明:该方法对多接闪器位置和高度优化设计的偏差不大于0.29 m;在该方法获得的接闪器位置和高度最优解条件下,预设的防护对象能够完全处于避雷针系统的保护范围之内,且防护对象与保护范围边界的最小间距不大于0.71 m,能够完全满足工程使用的需求。Aiming at the problem that the layout design of air-terminations in multiple lightning rod systems relies too much on engineering experience,based on the principle of least cost,an optimization model for the layout of air-terminations in multiple lightning rod systems is established by taking height and installation position of the air-terminations as the optimization variables.An optimization method for the layout of multiple air-terminations based on the genetic algorithm is proposed.The effectiveness of the proposed optimization method is verified by typical design cases.The results show that the deviation of the height and position of the air-terminations obtained by this method is not more than 0.29 m.All the preset objects to be protected can be completely covered within the protection range of the multiple lightning rod systems,and the minimum distance between the protected objects and the boundary of the protection range is not more than 0.71 m,which can fully meet the needs of engineering applications.
