某水库防洪能力复核分析

Review and Analysis of Flood Control Capacity of a Reservoir

水库由于长时间运行,防洪能力可能降低,给水库的正常运行埋下隐患。为了保障水库的安全运行,对水库工程的防洪能力进行复核,采用理论计算方法对水库的调洪演算以及坝顶高程等进行复核计算。通过分析计算,结果表明大坝坝顶(防浪墙)大于现行有关规范要求,溢洪道边墙高度不满足泄洪要求,需要采取相关措施提高水库工程的防洪能力,保障大坝安全。研究结果为水库安全运行提供参考。

Due to long-term operation,the flood control capacity of the reservoir may decrease,posing hidden dangers to its normal operation.In order to ensure the safe operation of the reservoir,the flood control capacity of the reservoir project is rechecked,and theoretical calculation methods are used to recheck the flood control routing and dam crest elevation of the reservoir.Through analysis and calculation,it was found that the dam crest(wave wall)exceeded the current relevant specifications.The side wall height of spillway does not meet the flood discharge requirements.Relevant measures need to be taken to improve the flood control capacity of reservoir projects and ensure dam safety.The research results provide reference for the safe operation of reservoirs.
