摘要
采用蒙特卡罗模拟法对液氨泄漏蒸气云爆炸过程中泄漏源参数的不确定性进行分析,并用Matlab数值计算软件绘出距爆炸中心一定范围内发生各级人员伤害风险的概率曲线图,通过该图可以直观地看出液氨泄漏蒸气云爆炸事故后果的影响范围以及冲击波在一定范围内对人体伤害不同等级发生的概率,这对于定量评估液氨蒸气云爆炸事故风险具有重要意义。
The parameter uncertainty of liquid ammonie leaking process was analyzed by means of Monte- Carlo simulation. The connection curves between personnel hurting risk level and determinate distance from the center of ammonie vapour cloud explosion（VCE） were described by Matlab. The hurting scope of ammonie VCE wave and accident risk probability at different levels were observed from these curves. This method is significant to assessing VCE accident quantitatively.
