Abstract: Taking the spillway reinforcement project of a hazardous reservoir as an example, the main problems of the spillway are analyzed, and the discharge capacity of the wide crest weir of the spillway, the height of the side wall, the anti-erosion capacity of the bottom plate and the stability of the side wall are checked. Based on the main problems, the specific reinforcement design scheme is proposed, which provides technical basis for spillway reinforcement and reference for similar projects.

Key words: hazardous reservoir, spillway, reinforcement, review, design

摘要： 以某病险水库溢洪道除险加固工程为例，分析了现状溢洪道存在的主要问题，复核了溢洪道宽顶堰泄流能力、泄槽段边墙高度、底板抗冲能力及边墙稳定性。根据实际存在的主要问题提出了具体的加固设计方案，为溢洪道的除险加固提供了技术依据，也为类似工程提供了经验参考。
