【摘要】 采用冲击波伤害-破坏准则,确定爆炸引起的人员伤害区域和建筑物破坏区域模型。结合GIS软件平台,编制爆炸灾害数值模拟程序,可以在GIS中以图形的形式给出设定条件下人员伤害区域及建筑物破坏区域的范围。并根据区域内的人员分布和建筑物造价、财产,给出定量的人员伤亡和经济损失应急评估,从而有效指导防灾减灾工作的进行。

【Abstract】 Models for areas of casualties and destructive buildings after explosion are determined by using the law of harm and destruction of shock waves. Based on GIS,numerical simulation programs of the explosion disaster are compiled. In setting the conditions,the dangerous area of casualties and distribution area of destructive buildings are given by the graphics form in GIS. Emergency evaluation of quantitative casualties and economic loss is given in accordance with the distribution of persons,building costs and the number of property in the area. Disaster prevention and reduction can therefore be effectively carried out.
