炸药爆炸事故的综合后果模型

讨论爆炸冲击波对建筑物的破坏作用，比较冲击波破坏半径和爆炸火球引燃木材半径的相对大小，提出炸药地面爆炸后果预测模型。该模型同时考虑爆炸冲击波、火球热辐射、房屋倒塌、爆源间面积、爆源间防爆程度、人员和财产分布状部等因素对事故后果的影响。模拟计算结果与事故的实际损伤情况基本相符。

A GLOBAL CONSEQUENCE MODEL FOR EXPLOSIVE EXPLOSION ACCIDENTS

This paper discusses the damage effect of explosion blast waves on buildings, compares the damage distances of the blast waves with the distance for wood to be ignited by expIosion fireballs, and presents a global model to predict the consequence of explosive explosions on ground. This model considers the influences of the following factors: the blast waves, the fireballs, the collapse of the buildings, the size and explosion-resisting degree of the explosion room, the population density and property density inside and outside the room. The predicted loss obtained by the model for a 40t TNT explosion basically agrees with the actual one with the same amount of TNT.
