摘要
为评价苯在运输过程中发生泄漏的灾害后果,采用事故后果模拟软件ALOHA分析苯槽罐车泄漏扩散范围和毒性区域,分析苯泄漏被点燃后火灾热辐射及冲击波超压的影响范围,使用人体脆弱性模型计算灾害区域内致死概率及个人风险值,结合Google Earth、Surfer软件绘制事故影响区域图。
In order to evaluate the disaster consequence of benzene leakage during transportation,the accident consequence simulation software ALOHA is used to analyze the diffusion range and toxic area of benzene tank truck leakage.The influence range of fire thermal radiation and shock wave overpressure is analyzed after the benzene ignition.The human vulnerability model is used to calculate the lethal probability and personal risk value in the disaster area.With Google Earth and Surfer software,the map of accident affected area is drawn.
