摘　　要：结合气体爆炸的特点 ,考虑和计算影响气体爆炸的几个主要因素 ,考察在海上天然气开发工程中 ,发生天然气泄漏点火后 ,燃烧爆炸的发展过程及产生的相应荷载作用 ,进而做了平台舱室因为爆炸荷载发生破损的变形分析 ,采用能量法建立了板的挠度公式 .计算结果与试验结果比较吻合 ,为油气田定量风险评估及事件升级分析奠定了基础 .In recent years safety and environmental checking have been paid more and more attention in the offshore oil and gas field construction.As one of the main aspects of the research.Quantitative Risk Assessment(QRA) is the focus of study.It is necessary to establish all kinds of models for QRA.In this paper the nature of gas explosion and the main factors affecting gas explosion of the combustion and explosion process must be studied when leakage and ignition happen.At last the deformation of the structure under the pressure due to gas explosion,and the results are compatible with the experimental results.A plate flexibility model is established by the energy method.The analysis can be the basis of escalation study and QRA of oil and gas field.
