| 摘 要： | 探讨了2种洪水风险理念,论述了现行防洪标准的含义及年标准洪水频率曲线的推求方法,提出了基于年标准洪水频率曲线诊断管运洪水防洪标准的新方法。介绍了基于Copula函数推求管运洪水的方法,研究了其风险结构。以马边河马边站洪水为例推求管运洪水,结果表明:基于Copula函数推求管运洪水选取的样本序列不完全符合防洪规范要求,所得到的管运洪水对应标准高于现行防洪标准,增大了洪水风险,会加大涉水工程的规模。

| Abstract: | Two concepts of flood risk are probed in this paper, and the exact meaning of current flood control standards and annual standard flood frequency curve are discussed. Based on annual standard flood frequency curve, a new method to diagnose flood control standards of the manage-flood is proposed. The approach of manage-flood calculation using Copula function is introduced, and its flood risk structure is studied. A case study of flood at Mabian station in the Mabian River shows that the sampling flood series in Copula function approach is not in accord with requirements of flood control; the obtained flood control standards of manage-flood exceed current flood control standards, flood risk would be increased, and water project scale would be enlarged. |
