入库设计洪水复核分析

水库除险加固,水文复核,至关重要。建库之前,一般是以坝址设计洪水作为水库防洪设计的依据,但水库建成后,设计洪水是从水库周边汇入水库,而不是坝址断面的洪水。实际资料表明,入库设计洪水与坝址设计洪水存在差别,不同的水库特性及不同典型洪水的时空分布,两者差异的大小也不同。用入库设计洪水作为水库除险加固设计依据符合实际情况。

Analysis of Reservoir Design Flood Rechecking

It is of vital importancefor reservoir reinforcement,hydrological rechecking.Before building a reservoir,it is generally based on the dam site design flood as the basis for the design of reservoir flood control,but after the completion of the reservoir,design flood is imported from around the reservoir rather than the flood of the dam site section.The actual data shows that the reservoir design floods and dam site design flood is different,and different reservoir characteristics and spatial and temporal distribution of a typical flood,the size of the differences between the two is also different.It is in line with the actual situation to take reservoir design flood as the basis of reservoir reinforcement design.
