向家坝堆渣对发电机组和泄水建筑物影响研究

Study on influence of slag heap on generators and water release structure in Xiangjiaba reservoir

按照向家坝水库蓄水计划和泄水设施运用原则,选取典型来水来沙条件,计算了向家坝库区的流场、含沙量和过机过坝悬移质级配,估算了向家坝水库库区内的粗颗粒起动粒径,分析了蓄水初期向家坝坝址上游右岸堆渣对向家坝发电机组和泄水建筑物的影响。

For the Xiangjiaba reservoir, the incoming water and sediment conditions were determined according to its filling plan and water release rules, and calculations were conducted for the flow velocity lind the concentration and gradation of suspended load in the passages of its generators and release structures The caculations are used for an evaluation of the maximum grain sizes of incipient motion in certain critical areas of the reservoir and an analysis on the influence of construction slag heap on the generators and release structures during initial impoundment.
