建立溃坝风险标准对于大坝风险评估和管理具有重要意义。目前，F-N曲线法在实践中得到广泛应用，利用F-N曲线分别建立大坝溃坝造成的生命、经济、环境、社会风险的判据。考虑到坝体溃决同时造成的两种或两种以上风险损失的叠加效应，提出了F-N曲面法建立坝体溃决综合风险准则。该方法建立命名的F-N曲面，通过这些曲面可以定义可接受、允许和不允许的综合风险区域。
It is of great importance to establish the dam failure risk criteria for dam risk assessment and management. Presently, the F-N curve method is widely applied in practice, in which the F-N curves are used for establishing the criteria for separate risks caused by the dam failure in life, economy, environment, and society respectively. In this paper, in consideration of the overlying effect by two or more types of risk losses resulting from the dam failure at the same time, the F-N curved surface method is presented for establishing the integrated dam failure risk criteria. In this method, the named F-N curved surfaces are established, and by these curved surfaces, the acceptable, the allowable, and the unallowable integrated risk zones can be defined.
