鱼塘水电站溢洪道底流消能设计

Design of Energy Dissipation by Hydraulic Jump for Spillway of Yutang Hydropower Station

贵州省遵义市鱼塘水电站岸坡式溢洪道底流水跃消能工设计中 ,比较了各种型式的消力墩、消力坎的作用及布置和常用的消力池型式。对矩形断面下挖式消力池与综合式B型消力池进行了对比分析 ,探讨了在大单宽流量、高流速情况下 ,如何合理运用消力墩、消力坎以改善消力池的工作状况 ,提高了消能效率 。

In the design of hydraulic jump dissipator for spillway of Yutang hydropower station, situated in Zunyi of Guizhou province, the effect and efficiency of Combined stilling pool is compared with simple stilling pool, the problems of using baffle piers and baffle sills to improve the effect and efficiency of stilling pool under condition of large unit discharge and high discharging velocity are researched.
