针对注汽锅炉的危险因素,基于对各基本事件发生的偶然性、不确定性,采用三角模糊数来表示事件发生的概率,进而求得顶上事件发生的概率。把事故树的理论分析和模糊数学两者结合起来,经过模糊运算得出各危险因素对注汽锅炉的破坏概率的区间值,确定模糊重要度,并对此进行排序,确定主次影响因素,并基于各危险因素绘制事故树,利用最小割集法和布尔代数法指出锅炉爆管的途径,给出引发该事故的模糊概率。分析了导致事故的原因,提出了注汽锅炉的保护措施。
針對註汽鍋爐的危險因素,基于對各基本事件髮生的偶然性、不確定性,採用三角模糊數來錶示事件髮生的概率,進而求得頂上事件髮生的概率。把事故樹的理論分析和模糊數學兩者結閤起來,經過模糊運算得齣各危險因素對註汽鍋爐的破壞概率的區間值,確定模糊重要度,併對此進行排序,確定主次影響因素,併基于各危險因素繪製事故樹,利用最小割集法和佈爾代數法指齣鍋爐爆管的途徑,給齣引髮該事故的模糊概率。分析瞭導緻事故的原因,提齣瞭註汽鍋爐的保護措施。

Based on the risk of steam inj ection boiler,and contingency and uncertainty of each basic events ,the triangular fuzzy number was used to show the probability of events,then get the top event probability.Combined with the fault tree analysis and fuzzy mathematics,through the fuzzy operation,the interval value of failure probability of hazards of steam inj ection boiler was obtained,and the fuzzy importance degree,sequence and main factors were determined.Drawing a fault tree based on various risk factors,using the method of minimal cut sets and Boolean algebra method,the boiler burst pathway tubes were showed,and fuzzy probability causing the accident was arrived.The causes of the accidents were analyzed,and protective measures of the steam inj ection boiler were proposed.
