摘要
以某大型水电工程为背景,通过考察其地形、地质、水力学、结构、施工和运行条件,经论证得出反拱型水垫塘与之最为协调,最适宜于做窄河谷大流量高拱坝的泄洪消能工,其优点突出.水弹性模型试验研究证明:反拱型底板抗浮稳定安全系数比平底板大得多,反拱型水垫塘是一种安全性选择.
Based on the topography,geological structure,hydraulics,hydraulic structure,construction and operating conditions of a large hydropower project,the counter-arch slab plunge pool is proved most fitted for the project of high arch dam energy dissipation in narrow valley under large discharge.The hydroelastic model experimental research indicates that stability safety coefficient against floataion of the counter-arch slab is much bigger than that of flat slab.The counter-arch slab plunge pool is the reasonable selection for safety.
