| 中文摘要:油气管道经常不可避免地穿越一些地形地质条件复杂区，而这些地区往往又是地质灾害的高发区，不同类型的地质灾害以不同的方式威胁着管道的安全运营。以普光气田输气管线为例：（1）建立了区域管道地质灾害风险评价模型与评价指标体系；（2）完成了普光气田输气管道地质灾害风险评价，将管道沿线地质灾害风险划分为地质灾害高风险区、较高风险区、中等风险区、较低风险区和低风险区5个不同等级；（3）根据地质灾害风险评价分区结果对管道进行地质灾害风险分段，将管道划分成了50个地质灾害风险等级段，其中：高风险段2段，较高风险段14段，中风险段20段，较低风险段14段。评价结果与实际相符，为管道灾害的预防、治理提供重要的辅助决策，为区域管道地质灾害风险评价提供了参考与借鉴。 |

| Abstract:It is inevitable for long-distance oil and gas pipelines to go through the areas with complex terrain and geological conditions, where are often high-risk areas of geological disasters, and different types of geological disasters threaten the pipelines safe operation in different ways. Taking the risk assessment case of Puguang gas field ground gathering and transportation gas pipeline, (1)Establishing the risk assessment model and evaluation index system of regional pipeline geological disasters. （2）Completing the risk assessment of geological disasters for gas pipeline, dividing the risk of geological disasters along the pipeline into 5 grades from high to low risk zones. (3)According to the zoning results of the geological disaster risk assessment, the pipeline geological disasters risks are divided into 50 risk sections, including 2 highest risk sections, 14 high risk sections, 20 medium risk sections and 14 low risk sections. The evaluation results are coincident with the actual situation, which provides important auxiliary decision-making for prevention and control of geological disasters along pipeline and give reference for regional pipeline geological disasters risk assessment. |
