【摘要】 运用漫坝风险分析理论,对紫坪铺水利枢纽漫坝风险进行了分析、计算,在确保水库漫坝风险小于10-6的前提下,提出汛限水位动态控制的建议。最终把汛限水位从850m抬高到855m,将使其多年平均发电量增加约1亿kW.h,从而提高了发电效益。更多还原

【Abstract】 The overtopping risk of Zipingpu Hydropower Project is calculated according to the theory of overtopping risk analysis.Under the assurance of dam safety reliability is higher than 99.999999%,the dynamic flood control level is suggested.The final flood control level is raised to 855.0 m from 850 m,so the annual average generation will increase by about 100 GW.h.更多还原
