摘　　要：泄洪消能型式选择是泄洪建筑物设计的主要内容,合理泄洪方案是整个水库枢纽安全防洪度汛的保障基础。为确保龙井湾水库泄洪建筑物能匹配开阔河谷、河岸泥岩夹层和泄流量小等特性,综合考虑坝型适应性、施工条件、农田影响和工程投资等因素,从泄水方式、消能防冲型式等方面,对泄洪建筑物布置及结构体型进行了分析计算。论证结果表明,坝身溢洪道自由溢流结合底流消能,具有良好工程匹配性和泄洪消能效果。The selection of flood discharge and energy dissipation types is the main content of flood discharge building design.A reasonable flood discharge plan is the foundation for ensuring the safety and flood control of the entire reservoir hub.In order to ensure that the flood discharge buildings of Longjingwan Reservoir can match the characteristics of open river valleys,mudstone interlayers on the riverbank,and small discharge flow,comprehensive consideration was given to factors such as dam type adaptability,construction conditions,farmland impact,and engineering investment.From the aspects of discharge methods,energy dissipation and erosion prevention types,the layout and structural shape of flood discharge buildings were analyzed and calculated.The demonstration results indicate that the free overflow of the dam spillway combined with bottom flow energy dissipation has good engineering compatibility and flood discharge energy dissipation effect.
