岩垱水库除险加固设计洪水分析

摘要:
采用暴雨资料及暴雨图表等方法对设计洪水进行复核,为岩垱水库除险方案和加固措施提供依据.在复核过程中,通过对暴雨特性、暴雨频率分析,利用设计点暴雨、设计雨型和设计面暴雨计算成果,采用扣损法进行产流复核分析,瞬时单位线法进行汇流复核分析,从而确定岩垱水库除险加固工程的设计洪水.通过与原设计洪水成果和地理位置邻近的其他水库洪水成果的对比分析,以及岩垱水库除险加固竣工投入运行3年来,经受住了洪水考验的事实说明本次洪水复核计算成果较为合理.

Abstract:
In this study, design flood recheck is made by use of storm data, rainstorm chart and other methods in order to provide evidence for risk-elimination program and reinforcement measures for the Yandang reservoir. After an analysis of rain storm characteristics and rain storm frequency, by using the calculation results of the design point storm, the design rainfall pattern and the design surface rain storm, the runoff is checked with the deduction loss method. And then the convergence check analysis is made by the instantaneous unit hydrograph method, and the design flood for the risk-elimination and reinforcement of this reservoir is determined. Comparison with the results of the original design flood and other reservoirs near the Yandang reservoir shows that the flood recheck results are more reasonable. Now, the Yandang reservoir has withstood the test of floods since the completion of the risk elimination and reinforcement project and has been put into operation for three years.
