| 摘 要： | 根据暴雨洪水特性和洪水地区组成分析了三峡水库入库洪水特性。选择代表洪水峰型、槽蓄量、洪水地区组成等不同影响因素的量化指标,采用投影寻踪法进行洪水分类。在此基础上,进行了入库洪水与坝址洪水关系研究。结果表明,分类别的入库洪水与坝址洪水系列具有较高的相关性,其相关关系可作为坝址洪水转换为入库洪水的参考依据,以更好地指导水库调度运行实践。

Classification of floods entering into reservoir and dam site flood of Three Gorges Reservoir based on projection pursuit |
| |
| Abstract: | Taking Three Gorges Reservoir as an example, the flood entering into the reservoir was analyzed according to the characteristics of rainstorm and flood and regional flood composition. By using different influential factors such as the peak pat-tern, flood storage capacity and regional flood composition, the flood was classified by projection pursuit method. It is shown that the classified flood into the reservoir are well related with dam site flood with high correlation coefficient, which can be used to convert the dam site flood to the flood entering into reservoir. The results can provide scientific support to practical reservoir oper-ation. |
