文中简述了石泉水电站及消力戽运行情况 ,观察到随着下泄流量的减小 ,消力戽从戽流形态向不稳定的挑戽过渡形态 ,又随着向挑流形态变化。提出在挑戽流转化时 ,要缓慢开启闸门 ,并规定了各孔的启闭程序以减少下游冲刷。文中还介绍了消力戽的检修及改造 ,提出了防止蚀损及蚀损补修措施。

The paper is a brcef description of Shiquan Power Station and the operation of the dissipation bucket observed in the site.Discharged water from the spillway changes from the bucket regine into an unstable jet flow with the decreasing of flow.A suggestion is proposed that during the transition stage opening of the gate should be slow,an order of opening and closing the gates on the spillway is set for reducing the scouring of the dawnstream river bed.The paper gives an illustration of examination and repair of the bucket and measures for protection against erosion.
