我国病险库坝数量多,规模大,急需处理。风险评估为衡量大坝安全提供了很好的途径。为此,根据风险评估的理论和方法,对病险库坝失事风险的评估方法进行了研究,阐述了包括风险识别、失事模式识别、风险分析、风险评价、风险评估有关概念及分析方法,提出了相应风险的处理措施,从而为病险库坝的除险加固提供决策依据。 In our country, the number of dangerous reservoirs and dams is large and in urgent need of treatment. Risk assessment provides a good avenue for measuring dam safety. Therefore, according to the theories and methods of risk assessment, the methods to assess the risk of failure of dams are studied and the concepts and methods of risk identification, risk analysis, risk assessment and risk assessment are expounded The corresponding risk management measures, so as to provide a basis for decision-making reinforcement of dangerous dams dam.
