摘 要: 通过建立西气东输工程陕西段地质灾害风险综合评估模型,应用层次分析法进行地质灾害风险分析评估,将地质灾害危险性与易损性有效地结合起来,利用综合指数法计算灾害风险值,对工程陕西段所遭遇地质灾害进行了排序,其中崩塌、滑坡灾害对管道的危害最大。 In this paper,the geological hazard risk synthetic assessment model for Shaanxi section of West to East Gas Pipeline Project is established.It applies the analytic hierarchy process to make the geological hazard risk synthetic assessment,in which geological hazard and vulnerability are associated together,and the synthesis index method is adopted to calculate the hazard risk value.The geological hazard degrees of Shaanxi section of West to East Gas Pipeline are sequenced,among them the collapse and landslide hazards have the biggest threat to the pipeline.
