摘    要:采用FDTD法和MPML吸收处界条件,对无限大钢筋网、钢筋混凝土层和素混送终凝土层的电磁脉冲屏蔽效能进行了时域全波分析。得出了典型结构尺寸钢筋网的电磁脉冲屏蔽效能及其随测点位置变化的规律,并对混凝土层的屏蔽效能以及钢筋交叉点焊接与否对钢筋网电磁脉冲屏蔽效能的影响进行了讨论。通过不同规格钢筋网屏蔽室模型和钢筋混凝土屏蔽室模型的电磁脉冲模拟试验,研究了钢筋粗细、间隔、钢筋交叉点焊接还是绑扎,有否浇筑混

关 键 词:屏蔽效能 电磁脉冲 钢筋混凝土 钢筋网

Abstract:It presents a time domain full wave analysis of infinity wire mesh reinforcement, reinforced concrete layer and concrete only layer in FDTD method. The EMP shielding effectiveness to some typical size of the reinforcement meshes were obtained. Two bonding methods for the cross points (welding and banding) of the reinforcement mesh are evaluated. Then the results of experiment were introduced. For studying the EMP shielding effectiveness, various shielding cell models are established, which are composed with mesh of reinforcement or reinforced concrete or concrete only. Some valuable conclusions are reached, which can be applied for engineering.
Keywords:shielding effectiveness  EMP  reinforced concrete  FDTD method
