摘　　要：为了减少事故发生,以苯储罐为例,对危险化学品储罐区的事故后果进行研究。总结了目前一些典型事故后果模型———火灾、泄漏事故后果模型,选定了相适应的应用模型,然后建立适当的几何模型,通过设定各个边界条件,模拟出毒气扩散的范围以及池火灾的热辐射范围,进而采用Statistical软件拟合出泄漏后浓度以及热辐射量与距离之间的关系,为安全间距的设定奠定了良好的基础,对储罐区的本质安全化管理具有很好的指导作用。In order to reduce the accident,this article takes the benzene storage tank as an example,to conduct research on the dangerous chemical storage tank areas accident consequences.This article has summarized some typical accident consequences model-fire,the divulging accident consequence model,selected the corresponding model and established suitable geometric model;through establishing each boundary condition,the proliferation scope of poison gas is simulated,as well as the pond fires heat radiation scope,consequently using the statistical software to find out the density after divulging and the relation between the thermal exposure and the distance,so as to lay the good foundation for the safety space setting,and give the good instructions for the essential safety management.
