摘要
当毒气泄漏时 ,正确的疏散指挥是避免和减少人员伤亡的关键 ,而选择最佳疏散路线又是正确指挥的前提·基于扩散理论和毒物伤害模型之上 ,把事故伤害范围划分为致死区、重伤区、轻伤区和吸入反应区·接着 ,讨论了疏散路径的可行性和当量长度模型 ,提出了通行难易程度系数和危险系数的概念 ;然后根据网络理论的k最短路解法 ,讨论了两点间k条最短疏散路径的求法·最后 ,以某市化工厂的氯气泄漏为例 ,求出从泄漏点到疏散安全地点的 3条最短路线的当量长度分别为 2 4780m ,2 72 2 1m和 386 79m·
Based on the theory of the gas diffusing and the toxic injury model, the area of accident harm was divided into the death zone, the severe harm zone, the slight harm zone and sucking reaction zone. The model of equivalent length, the feasibility of the evacuation route and the concepts of the coefficient of pass difficulty, ease and danger were put forward. The method to solve the k shortest route between 2 spots is discussed on the basis of the network theory. The length of three shortest route is respectively 24?780?m, 27?221?m and 38?679?m from the chlorine leakage spot to evacuation safety zone in a chemistry factory.
