海上油气生产设施结构对爆炸的响应

摘要

In recent years, safety and environmental checking is being paidmore and more attention by our government in offshore oil and gas field construction. Quantity Risk Assessment (QRA) as the main aspects of the above jobs is becoming the focus to study. It is very necessary to establish all kinds of models for QRA. In this paper, the deformation of the structure under the pressure from gas explosion was analyzed, and the results is compatible with the experimental ones. A plate flexibility model is established with energy method. The analysis will be the foundation of escalation study and QRA of oil and gas field.%近年来，我国海上油气田的安全检查和环境检查已成为政府部门极为重视的问题，海上油气田定量风险评估作为其中不可少的组成部分也成为研究的焦点之一，为此所需的各种试验研究模型正在建立。为了对平台舱室因爆炸荷载发生破损的变形进行分析，采用能量法建立了板的挠度公式，其计算结果与试验结果比较吻合，为海上油气田定量风险评估及事件升级分析奠定了基础。
