摘　　要：储罐是石油化工行业常用的储存设备,经常储存易燃、易爆或有毒物品,在使用过程中,一旦储罐失效其后果非常严重。通过对引起储罐失效的因素进行系统分析,建立了以储罐失效为顶事件的事故树。通过分析,得到了储罐失效树的各阶最小割集,确定了引起储罐失效的灾变风险源,计算出基本事件的结构重要度系数,并进行了相对重要程度排序,提出了相应的改进措施以确保储罐平稳安全运行。Storage tank is commonly- used equipment in petrochemical storage and the medium is generally inflammable, explosive or poisonous, so once it is failure at work, the consequence is very serious. This paper analyzes the causes of the failure of storage tank and establishes the fault tree model. Based on the analyses, the minimum cut set of each steps of the fault tree is given, the important causes of the failure of storage tank are found out, the structure importance degree coeffecient of basic events is calculated, the relative important degree sequence is done and the relative improvement measures are raised to ensure the safe operation of storage tank.
