摘要: 随着石油资源的日益短缺和国家能源战略的调整,环保要求和汽车技术的不断提高,燃气车辆不断增多,与之相对应的车用加气站的数量也越来越多。但是接连发生的加气站燃气泄漏与火灾事故使得加气站的使用安全问题成为日益关注的问题。当加气站出现燃气泄漏与火灾事故时,天然气未立即着火可形成爆炸气体云团,遇火就会发生爆炸,在危险距离以内,人会受到爆炸冲击波的伤害。重点将对CNG加气站爆炸事故后的交通疏散条件制定分级标准,结合实例采用计算机软件仿真疏散分析,对以后进行新建加气站的安全评估分析工作开展提供定量依据。

Abstract: With the shortage of the gasoline resource day by day,the adjustment of county’s energy strategy,environment protect requirement and the continuous progress of the automobile technology,more and more automobiles are designed on the CNG as their fuel and corresponding CNG stations are increasing at the same time.But the consequential accidents such as the leakage of the gas and the fire disaster make the security of the CNG station become a serious problem which people pay more and more attention on it.If the gas is not fired immediately,it may construct the gas cloud cluster and will explode when it comes out a fire,and people in a certain distance may be wounded by the shockwave also the architectures in the dangerous range will be destroyed.This paper contributes to formulate the evacuate conditions for pedestrian after the explosion accident happening and also provides the basis for evaluating the new constructed CNG stations.
