为了在三维地理信息系统中实现空爆核武器对城市建筑群毁伤效应的可视化,对核爆相关理论和已有经验公式进行了研究,归纳得出空爆炸冲击波对城市建筑物毁伤效应的数学模型;以地理信息系统技术为基础,以离散拟合思想为依据,提出了空爆冲击波对大规模城市建筑群毁伤效应的物理模型;提出利用四面体剖分模型对毁伤后的建筑物进行表达。文中提出的模型为空爆核武器对城市毁伤效应的科学可视化提供了技术支持。

In order to realize the visualization of the damage effect of nuclear blast shock wave on buildings in 3D GIS, the correlative theory of nuclear blast and the existing experiential formulae were studied on, a series of mathematical models was concluded. On the basis of the technique of 3D GIS, the theory of discrete was combined; a set of physical model was proposed to describe the damage effect of nuclear blast shock wave on buildings. The TEN models were provided to describe the damaged buildings. The models given in this paper provide technical support for the visualization of the damage effect of nuclear blast shock wave on buildings in 3D GIS.
