三里坪水利枢纽工程设计洪水复核分析

南河流域洪水特性受台风雨影响，表现为洪高量大，汇流快。为了对三里坪枢纽工程验收提供设计洪水复核成果，通过对坝址附近控制站—台口（二）水文站多年实测资料分析，并进行历史洪水调查，结合历史洪水与实测洪水组成不连续系列进行频率分析，得出坝址设计洪水成果，对原有初步设计成果加以复核。复核结论认为，依据台口（二） 站计算的设计洪水成果可作为三里坪水库的设计依据。其分析计算方法可供类似工程区域设计洪水计算参考。

Recomputation of design flood of Sanliping Hydro -junction

The floods in Nanhe River Basin have the characteristics of large quantities of flood discharge and quick confluence influenced by typhoon rain.In order to provide the recheck results of design floods for the acceptance check of Sanliping Hydropower Project,by analyzing the many years data of Taikou(II)hydrological station and surveying the historical floods,frequency analysis is conducted with discontinuous series comprised of the historical floods and the real floods.The results of design floods at dam site is obtained,which can check the preliminary design results.The checking results show that the results of design floods calculated by Taikou(II) station can be the design basis of Sanliping Reservoir and the calculative methods are available for design flood calculation in similar projects.
