摘要
介绍百色水利枢纽RCC主坝表孔宽尾墩联合消能工设计、试验研究成果。该工程泄洪流量大、下泄功率高、河床水深偏浅且地质条件较差,通过研究,确定采用"表孔宽尾墩+中孔跌流+底流式消力池"新型联合消能工,溢流面设置掺气坎,减轻溢流坝面气蚀破坏,消力池底板厚5~8m,附加底板锚筋,满足安全需要。
Design, testing and research results of surface spillway tail-flaring pier joint energy dissipator of the RCC main dam of Baise Multipurpose Dam project is introduced. This project is characterized by low riverbed water depth, relatively poor geological condition, high flood discharge and under pour power. After research a new joint energy dissipator is determined, composed of surface spillway tail-flaring pier, breast spillway flow drop, underflow stilling pool. Aeration step is designed on the spillway surface to alleviate possible damage to dam surface from cavitation. Base slab of stilling pool will be 5~8m thick and designed with additional base slab anchorage bar, so as to meet safety requirement.
