摘要
南盘江属于南方多沙河流,天生桥二级水电站首部进水口是低坝小库容水库取水,在天生桥一级水库建成之前能否解决好引水防沙难题,是工程建设成败的关键。通过选择较理想的坝址、利用一个开阔河弯的末端布置引水防沙设施,深入研究水沙条件,优化防沙设施布置,开展泥沙模型试验验证,实行水库合理调度运行,较理想地达到了引水防沙效果。
The head inlet of the Tianshengqiao Cascade-Ⅱ Hydropower Station is located at a river bend of the Nanpan River, which is a sediment-laden river in the south of China. How to solve the problem of water diversion and sediment control is the key to construct the project successfully before the Tianshengqiao Cascade-Ⅰ Hydropower Station is built. The intention of sediment prevention design is achieved ideally through these waysi selecting a suitable dam site and using water diversion and sediment control at the end of a wide river bend; analyZing flow and sediment thoroughly; optimizing the iayout of sediment prevention;doing sediment model test;operation reservoir reasonably.
