| 摘 要： | 银盘水电站三期明渠截流期间，由河床溢流坝段预留缺口分流，为提高三期围堰挡水发电水位，将预留的4孔缺口提前封堵2孔，导致三期明渠截流落差达到5.49 m，截流难度增加。通过水力学试验与计算分析，设计研究了龙口位置与宽度、堰顶高程、戗堤分段进占方案，以及抛投料选择等，实际截流施工中，采取充分利用材料抗冲特性，加大抛投强度等措施，保证了截流施工的顺利完成。

| Abstract: | During the third stage of river closure of Yinpan Hydropower Station,the gaps of the spillway dam were preserved for flow diversion.In order to increase cofferdam water level for power generation,2 gaps were closed in advance,which resulted in water fall of 5.4 m in the third stage of river closure and made the construction more difficult.Through hydraulics test and calculation analysis,the location and width of the closure gap,the scheme of stepped occupying the closure dike on the top of cofferdam and sel... |
