摘　　要：结合我国实际,综合考虑水库大坝自身安全以及潜在的溃坝后果,研究提出了一套相对简单和快速的水库大坝风险等级评估方法,包括风险指数快速评估方法、风险评分方法、定量风险评估方法。介绍了该套方法的分析思路与具体内容,详细阐述了对各类评估指标进行赋值的依据或计算方法,并结合某省13座病险水库工程进行了示范性应用。Taking the real condition of China as well as safety of reservoir dams and potential hazard caused by dam failure into consideration, relatively simple and efficient methods for evaluating risk level of reservoir dams have been developed, such as rapid assessment of risk index, risk scoring and quantitative risk assessment. Analytic concepts and specific contents of these methods are introduced with detailed explanation of assignment basis and calculation method for these indicators. Pilot projects have been implemented in a province with selection of 13 reservoirs for risk assessment demonstration.
