| 摘 要： | 本文以紫坪铺水库为例,在建立洪水过程随机模型的基础上,用统计试验手段探讨了设计洪水过程线作为水库防洪安全设计依据的适用性。结果表明:设计洪水过程线法能导致水库实际防洪安全标准偏离指定设计标准(偏高或偏低)。影响偏离的主要因素为时段洪量设计值的抽样误差和典型过程线的形状。现行方法的适用性是有条件的。

| Abstract: | The applicability of design flood hydrograph as a basis of the design of reserviors safety withstanding flood has been examined by using statistical experiment. This examination is based on the stochastic flood model which was developed for the hydrological design of Zhi Ping Pu reservior. The results have shown that design flood hydrograph may lead the actual criterion of reservior safety withstanding flood to deviate seriously from the specified one. The main factor which may have a strong impact on such a deviation is the sample errors of certain flood volumes in a flood hydrograph. The prerequisite of the applicability of design flood hydrograph is also discussed in this paper. |
