本文针对龚嘴水电站等八个大型工程采用面流消能运行的调查及有关模型试验资料,并参考前人研究成果,对面流消能运行中的主要经验和存在问题,进行了简要综合。重点地对控制流态、防止冲刷、磨损和下游岸坡护理等三个问题进行了分析讨论,并分别对改善流态、防冲、防磨、防波、减波和岸坡护理提出了具体意见和建议。本文最后指出,八个大型面流消能工程的运行情况,总的来说是成功的。
In this paper, based on the investigation and related model test data of facet energy dissipation operation of eight large projects such as Gongzui Hydropower Station, and based on the research results of predecessors, this paper briefly summarizes the main experience and existing problems of facet energy dissipation operation. The three issues of controlling fluid flow, preventing erosion, abrasion and downstream slope care were analyzed and discussed, and concrete suggestions were put forward to improve fluid flow, anti-erosion, anti-abrasion, anti-wave, wave reduction and slope nursing Opinions and suggestions. Finally, this paper points out that the operation of eight large-scale surface flow energy-dissipating projects is generally successful.
