针对低闸引水开发式电站库小、沙多、落差大、泥沙严重的问题,以塔坑水电站为例,通过模型试验验证了枢纽布置,并修改和优化了引水防沙设施。试验结果表明,电站枢纽布置合理,优化后的引水防沙设施效果理想,可满足工程规划设计要求。 Aiming at the problem of small sluice, sand more, big drop and serious sediment in low sluice hydropower station, taking the tower pit hydropower station as an example, the layout of the hub was verified through model test and the water diversion and sand control facilities were modified and optimized. The test results show that the layout of the power station is reasonable and the optimized water and sediment control facilities are effective and can meet the requirements of engineering planning and design.
