摘　　要：运用故障树分析法对引江济淮工程(河南段)泵站系统长期服役主要风险源及作用关系进行识别,以归纳的风险要素类别为基础,采用层析分析法和专家咨询法依次确定泵站系统长期服役风险评估指标、指标权重和风险率等级赋分标准,建立引江济淮工程(河南段)泵站系统长期服役风险评估方法;基于收集的泵站系统工程特性、防洪设计参数等资料,运用构建的评估方法对袁桥、赵楼、试量、后陈楼和七里桥泵站长期服役风险进行评估。结果表明:各级泵站长期服役风险率均在(1,2]级,总体风险较低。然而,由于泵站多为串联关系且上游泵站的设计规模往往大于下游泵站,一旦上游泵站失效,下游泵站均受影响,泵站设计规模的空间差异和结构关系将显著增加系统运行风险,在后续的风险控制及运行管理中需加以重视。The Yangtze-to-Huaihe River Water Diversion Project is a significant strategic water resources allocation and comprehensive utilization project across river basins and regions.In this project,the pumping station system is characterized by its large scale,complex structure,and wide range of water supply areas.During the long-term service duration,the system faces various uncertainties and risks.When the fault occurs,the normal operation of the system will be affected,which may cause abnormal water supply,and even lead to a series of ecological and social problems,or even casualties.Therefore,the long-term service risk assessment of the cross-basin long-distance water diversion engineering’s pumping station system is crucial to adequately estimate various risks and understand the overall risk level,which is essential for the development of scientific and rational risk management measures.Aiming at the long-term service risk assessment of the pumping station system of the Yangtze-to-Huaihe River Water Diversion Project(Henan Reach),the fault tree analysis method is employed to identify the major long-term service risk sources and corresponding relationships that may impede the normal pumping function,considering the insufficient water lifting efficiency and safety threat to engineering.Based on the categorized long-term service risk factors,considering operational conditions,equipment quality,technological status,and engineering safety,a multidimensional approach is adopted,in which the analytic hierarchy process and expert consultation methods are utilized to determine the evaluation indicators,indicator weights,and risk rating criteria for the long-term service risks of the pumping station system.This establishes an assessment method for the long-term service risks of the pumping station system of the Yangtze-to-Huaihe River Water Diversion Project(Henan Reach).Based on the collected measurements consisting of engineering characteristics and design flood control parameters of the pumping station system in the Ya
