常州市埋地天然气管网多准则安全评价

Multi Criteria Safety Evaluation of Buried Natural Gas Pipeline Network in Changzhou

我国城市规模的扩大和天然气需求的增加,导致城市埋地天然气管网越来越复杂,城市埋地天然气管网的安全对于保障城市的可持续发展至关重要。为了对常州市埋地天然气管网做出准确的安全评价,分析了导致埋地天然气管网破坏的影响因素,构建了基于地理信息系统的多准则安全评价的权重线性组合法模型,运用层次分析法计算了各影响因子的权重,得到了常州市埋地天然气管网安全评价结果。依据计算结果,分析了常州市埋地天然气管网的高风险区域,并为降低这些区域的破坏风险提供了工程措施建议。

With the expansion of urban scale and the increase of natural gas demand,buried natural gas pipeline network has become more and more complex.The safety of buried natural gas pipeline network is essential to ensure the sustainable development of cities.In order to make an accurate safety evaluation of the buried natural gas pipeline network in Changzhou,the influencing factors leading to the destroy of the buried natural gas pipeline network are analyzed,and a weighted linear combination method model based on multi criteria safety evaluation of geographic information system is constructed.The weights of each influencing factor are calculated by AHP,and the safety evaluation results of buried natural gas pipeline network in Changzhou are obtained.According to the calculation results,the high-risk areas of buried natural gas pipeline network in Changzhou are analyzed,and the engineering measures are proposed to reduce the damage risk of these areas.
