| 摘 要： | 运用区间分析理论,在综合考虑起调水位、洪水、风浪、坝顶高程等方面不确定性的基础上,建立土坝漫坝风险模型,给出漫坝风险区间和风险度计算方法,并对风险度0,1]采用5级制划分,为漫坝风险评判提供依据。实例工程计算结果表明,区间分析法是漫坝风险评判中行之有效的方法。

| Abstract: | Based on studying uncertainties of the water level for flood control, floodwater, wind waves and crest elevation, this paper applies the interval analysis theory to establish the model of overtopping risk of earth dam and gives the calculating methods of overtopping risk interval and threshold. The risk threshold is divided into five grades, which provides the basis for overtopping risk evaluation. The analyzed and calculated results from a actual project indicated that the interval analysis method is feasible to evaluate overtopping risk. |
