| 摘 要： | 高压输气管道事故会导致严重后果，为了减轻管道事故的影响，有必要对输气管道失效后果严重区进行分析。采用事件树分析法进行风险分析并建立了数学模型，包括火灾模型、有效释放率模型、热强度极限值、危险区域等式四部分。通过对已报道的输气管道严重事故的预测破坏程度和实际破坏程度进行比较建立模型的有效性。

| Abstract: | Severe consequences may result from failures in high-pressure natural gas pipelines. It is necessary to analyze high consequence areas in gas pipelines to mitigate effects of accidents. Accident tree analysis is applied to risk analysis and a mathematical model is established, including fire model, effective release rate model, heat intensity threshold and hazard area equation. Pipeline incident reports are reviewed and a basis is provided for evaluating the validity of the model by comparing the expected extent with actual one. |
