Study of reaction of dredging mouth bar on flood discharging and sediment sluicing in lower river channel of the Yellow River;

黄河口拦门沙疏浚对尾闾河道泄洪排沙影响的研究

Taking into consideration the flood,geological and tailrace conditions,as well as the layout of the project,the way of flood discharging and energy dissipation of the project complex was optimized at the construction details design stage by reference to the flood discharging and energy dissipation design experience of other medium-sized hydropower projects of its kind at.

在参考国内中型水电站的泄洪消能设计经验后,结合土卡河的洪水、地质条件、尾水条件及枢纽布置特点,在施工详图阶段,对枢纽的泄洪消能方式进行了优化,采取了台阶式溢流坝面加平尾墩及戽式消力池方案,水工模型试验表明该方案是合理的。

The study includes the optimal layout of the flood discharging energy dissipation, the hole arrangement and its type in the dam body, the scour balance and energy dissipation mechanism of water cushion pond, the effect of the flood discharging vi.
