摘要
巴底水电站首次在岸边溢洪道中设置“X”形宽尾墩，通过模型试验验证此方案既能充分消能，减小泄洪雾化，又能缩短消力池长度，减小工程量；且下游水面平稳，冲刷轻微；同时减轻了对生态环境和枢纽区边坡的破坏和影响。巴底水电站岸边溢洪道中的宽尾墩布置在中间隔墩末端，且流速达20～22m／s左右，突破了原本只能在堰顶墩末布置且流速在15m／s左右的限制，为相关工程提供了新的研究方向。
The X-shape flaring pier is firstly used in the bank spillway of Badi Hydropower Station. The model tests show that the X-shape flaring pier scheme can dissipate energy and reduce discharge atomization, but also can shorten the length of stilling basin. The scheme of flaring pier has slight scouring on downstream channel and the impact of bank spillway on ecological environment and bank are also reduced. The flaring piers in Badi Hydropower Station are arranged in the end of middle isolated pier, and the flow speed through the flaring pier is about 20-22 m/s which exceeds the limit of 15 m/s when the flaring pier used in weir top. The application of X-shape flaring pier in bank spillway of Badi Hydropower Station provides a new research direction for related projects.
