摘　　要：利用CST软件建立轨道交通系统内各强电设备的数学仿真模型,对轨道交通站内的电磁辐射分布情况进行仿真计算;根据现场类比测试的结果对仿真模型进行修正,完善理论模型,使其能准确反映轨道交通系统内的电磁环境状况。通过建模、测试验证、修正模型、再分析计算、再测试验证等一系列过程,结合弱电设备自身的抗扰度标准,提出了正常工作条件下强弱电设备间的最小距离,以及各设备房间的合理布局,达到有效利用车站空间资源,节约设备用房面积及投资等目的。Based on CST software, the models of the heavy current facilities in the subway system are built and the simulation to acquire the distribution of electro- magnetic interference（EMI）is completed. Comparing the results of the simulation with the corresponding results of the actual measurement, and then modify the models until the simulation could reflect the situation of electromagnetic field around the heavy current facilities correctly. With the procedure of actual measurement, modeling, simulation, analysis and modification, the minimum distance between the heavy and weak current facilities in the subway station under the normal working condition could be proposed. A more reasonable layout of all facilities could also be acquired so that the resource of the rooms could be saved and the ad ministration of the whole station could be easier.
