摘要

KLBL水电站溢洪道出口挑流鼻坎,原设计方案采用单曲挑坎形式,经试验验证下泄流量不满足设计过流能力,严重影响了溢洪道的安全运行。笔者在理论计算的基础上,结合水工模型试验,对溢洪道挑坎体型进行了改进优化,提出采用双曲扩散挑流鼻坎体型,通过模型试验分析,说明设计合理。
        The spillway outlet flip bucket of KLBL hydropower station, the original design adopted the form of single curvature bucket. The test verifies that the discharge flow is not satisfied with the design flow capacity, which seriously affects the safe operation of the spillway. On the basis of theoretical calculation and combined with hydraulic model test, the authors have improved and optimized the shape of spillway bucket, and proposed the use of hyperbolic diffusion flip bucket shape. The model test analysis shows that the design is reasonable.
