摘　　要：基于"滚球法"原理,利用GPU的高性能并行计算能力,模拟半径为R的球体,沿需要防直击雷的各个方向滚动,将不触及的范围通过Delaunay法构造平滑曲面,计算出各种防雷保护设施的正确保护范围,补充了GB 50057—2010《建筑物防雷设计规范》中没有提及的不等高接闪杆、避雷带的联合保护的计算方法,且该方法具有较高通用性、准确性,以及计算高速性的特点。Based on the principle of rolling ball method,the correct protection scope of various lightning protection facilities is calculated by using the high performance parallel computing ability of GPU,simulating the sphere with diameter of R,rolling along all the direction needing lighting protection,constructing the un-touched scope to smooth hook face with Delaunay method.The calculation method of joint protection with different height lightning rod and lightning strip missed in the standard of GB 50057--2010 of Code for Design Protection of Structures Against Lighting is supplemented.The method is characterized with higher universality,accuracy and high speed for calculation.
