摘　　要：燃气泄漏事故伴随着爆炸、中毒等多项风险威胁,造成经济损失和伤亡损失。利用Ansys/Bow-Tie建立扩散模型与分析计算模型,将燃气泄漏定性与定量分析。研究表明:在定性变化中,燃气泄漏后泄漏区域的燃气扩散速度呈指数大模块式上升,扩散速度极快;在定量变化中,燃气泄漏的主要风险来源于巡检不足以及检维修不及时可能发生的概率最大,分别为0.039和0.046,通过加装有毒有害气体仪表报警监测群和对大风险问题加强监控可为风险管控提供帮助。Gas leakage accidents are accompanied by a number of risk threats such as explosion and poisoning which brings about economic losses and casualty losses.In this paper,Ansys/Bow-Tie are adopted to establish diffusion model and analytical calculation model to analyze gas leakage qualitatively and quantitatively.The study indicates that in the qualitative variation,the gas diffusion rate increases exponentially in large modular in the leakage area and the diffusion rate is extremely fast.In the quantitative variation,the main risk of gas leakage comes from insufficient inspection and lack of timely overhaul with the highest probability of 0.039 and 0.046 respectively.It can be helpful for risk control to install toxic and hazardous gas instrumentation alarm monitoring group and strengthen the monitoring of large risk issues.
