摘要
对富川水库泄洪洞泄流流量及其消能防冲型式进行理论计算设计,后采用水工模型试验对理论计算进行验证,根据试验结果优化修改理论设计。调整理论计算的泄洪洞出口断面,并对挑流消能的鼻坎型式进行优化修改。优化后设计方案可有效改善泄洪洞的水力条件,消除洞出口负压,通过改变挑流水流方向,可减小水流对下游岸坡的冲刷。
The theoretical calculation design of the discharge flow and the energy dissipation and anti-shock type of the flood discharge tunnel of Fuchuan Reservoir is carried out. The hydraulic model test is used to verify the theoretical calculation. The theoretical design is optimized and modified according to the test results. The theoretical calculation of the exit section of the spillway tunnel is adjusted, and the nose-hook pattern of the pick-up and energy dissipation is optimized and modified. The optimized design scheme can effectively improve the hydraulic conditions of the flood discharge tunnel,eliminate the negative pressure problem of the tunnel outlet, and reduce the flushing of the downstream bank slope by changing the direction of the picking water flow.
