新疆乌鲁木齐市高压燃气管网风险评估研究

针对城市高压燃气管线的安全风险,利用定量评估方法对其进行风险分析.建立了由管网脆弱性指标、事故诱因指标、事故后果指标以及各指标的权重共同组成的定量评估指标体系.基于该定量评估指标体系,对乌鲁木齐市50余条高压燃气管线进行了定量风险评估,为城市燃气管网安全管理提供数据支持,为建立预测预警系统和防灾减灾机制提供依据.

The Research on Risk Assessment of High Pressure Gas Pipeline Network in Urumqi,Xinjiang, China

In recent years, as the project of changing fuel from coal to natural gas progress in Urumqi of China, a large number of high-pressure gas pipelines enter into the center city, bring huge risk to city public safety. In order to quantitatively assess the risk of gas pipelines, the quantitative evaluation index system, which includes inherent risk index, causation index, consequence index and the weight of each index. Based on the quantitative evaluation index system, more than 50 high pressure gas pipelines were conducted quantitative risk assessment in Urumqi. The assessment results can provide data support for the management of city gas pipeline network, and also can provide basis for establishing forecasting systems and mechanism of disaster prevention and mitigation.
