    Abstract:3D numerical model of building is established by using earthing and electromagnetic field CDEGS software. Electromagnetic field change and its hazards to personnel, equipment and systems when buildings suffer lightning stroke are preliminarily analyzed using the soil resistivity and soil stratification model,in combination with lightning characteristic parameters and lightning protection measures for buildings,so as to provide data support for risk assessment of lightning hazards and lightning protection measures for super high-rise buildings.
    Key words:super high-rise buildings;lightning electromagnetic environment;electromagnetic field;CDEGS software;lightning data;thunderstorm day;lightning current waveform;stratification model of soil structure
 
    摘 要:采用接地与电磁场CDEGS软件建立建筑三维数值模型,利用土壤电阻率和土壤分层模型,结合雷电特征参数和建筑的防雷措施,初步分析其遭受雷击时周边的电磁场变化及对人员、设备和系统的危害,为超高层建筑雷电灾害风险评估及雷电防护措施提供数据支撑。
