摘要
兰成原油管道途经区域地质环境条件复杂、地质灾害类型多样,对管道工程和人民生命财产安全潜在危害严重。为了应对各种地质灾害风险,基于GIS技术构建了区域管道地质灾害风险评价模型与评价指标体系,将管道沿线地质灾害风险划分为地质灾害高风险、较高风险、中等风险、较低风险、低风险5个等级。对兰成原油管道沿线地质灾害风险进行评价,根据地质灾害风险评价分区结果,将管道划分成53个地质灾害风险段。评价结果与兰成原油管道实际情况相符,为其地质灾害预防、治理提供了重要的辅助,也可为其他管道的地质灾害风险评价提供参考。(图3,表5,参20)
Along Lanzhou-Chengdu Crude Oil Pipeline,the geological conditions are complex with various geological hazards,which brings about serious potential hazards to the safety of pipeline engineering and people’s life and property.In this paper,a risk assessment model and evaluation index system of regional pipeline geological disaster were established based on GIS technology to cope with the hazards of various geological disasters.Then,the risk of the geological disasters along the pipeline was divided into five grades,i.e.,highest risk,higher risk,moderate risk,lower risk and lowest risk.Finally,the risk of the geological disasters along Lanzhou-Chengdu Crude Oil Pipeline was evaluated,and the pipeline was divided into fifty-three risk sections of geologic disaster according to the zoning results of geological hazard risk assessment.The evaluation results are consistent with the actual situations of Lanzhou-Chengdu Crude Oil Pipeline.The research results play an important auxiliary role in the prevention and treatment of geological hazards,and also provide a reference for the risk assessment on the geological disasters along other pipelines.(3 Figures,5 Tables,20 References)
