摘　　要：设计参数的取值对于泄水建筑物能否在服役期内安全运行十分关键。如果忽略建筑物的结构类型和风险级别,会增加大坝失事风险,威胁下游人民财产安全。以开阳县詹家湾水库为例,对其泄水建筑物设计过程进行了探讨。介绍分析了溢流堰剖面设计,计算WES实用堰泄流能力,详细分析了泄槽水面线设计、消能设计过程,研究方法可为相关工程提供参考。The selection of design parameters is crucial for ensuring the safe operation of spillway structures during their service period.Neglecting the structure type and risk level of the structures can increase the risk of dam failure,posing a threat to the downstream people and their property.Taking Zhanjiawan Reservoir in Kaiyang County as an example,the design process of its spillway structures has been explored.This includes discussing the profile design of the spillway crest,calculating the discharge capacity using the WES practical weir formula,and providing a detailed analysis of the design process for the energy dissipation of the spillway chute water surface.The research methodology can serve as reference for related engineering projects.
