摘要
综合考虑可能引发LPG储罐火灾、爆炸事故的各个基本因素,构建事故树。首先计算结构重要度系数进行定性分析;其次,在专家打分法的基础上,运用三角模糊数来表征基本事件发生概率;应用模糊重要度对事故树基本事件进行排序,确立影响事故的主要因素为安全阀失效和静电火花,提出相应的改进措施以提高LPG储罐的运行可靠性。
It builds the fault tree on the basis of considering each factor for incurring fire disaster and explosive of LPG tanks. Firstly, calculates importance of structure for qualitative analysis; Secondly, on the basis of experts＇ marking, shows probabilities of incidents applying triangle fuzzy numerals; arranges the incidents applying importance of fuzzy, and establishes the main factors for this accident are losing efficacy of safety valve and static spark. At last puts forward the relevant improving measures to enhance reliability for LPG tanks.
