闹德海水库防洪标准复核分析评价

Analysis and evaluation on flood control standard review of Naodehai Reservoir

针对闹德海水库近年来流域来水量少,泥沙淤积量大,严重影响水库防洪安全的实际,利用延长的水库实测水文资料系列和现行调洪计算条件进行设计洪水复核、坝顶超高复核和泄洪建筑物安全复核。结果表明:大坝实际抗洪能力能够满足原设计防洪标准和国家现行规范要求,发生最大泄量时可安全下泄。

The prolonged reservoir measured hydrology data series and current conditions of flood regulating calculation are adopted for reviewing design flood,dam crest super-elevation and overflow structure in view of the practice that less river basin incoming water and high silt sedimentation in Naodehai Reservoir seriously affect reservoir flood control safety in recent years.The results show that the actual flood resistance capacity of the dam can meet the requirements in original design flood control standards and national current standards,and safe discharge can be achieved during maximum discharge.
