| 摘 要： | 某闸坝式水电站坝址覆盖层深厚,河道欠宽阔,发电引用流量比例较高,受调节库容限制,库区泥沙将很快输移到达坝前,引水防沙问题突出。本文对施工围堰作为其电站枢纽引水防沙体系的效果进行了水工模型试验研究和分析。对四种挡沙坎布置型式进行了对比试验研究。表明,利用原有挡水围堰,结合纵向挡沙坎与排沙底孔联合作用既有利于施工方便,拉沙效果又较好,可达到电站＂门前清＂,较好的解决了大流量闸坝式电站的引水与防沙之间的矛盾。本研究成果的成功实施可减少工程投资,缩短工期,尤其对于在低水头、大单宽的多沙河流上修建的闸坝工程具有较好的借鉴意义。

| Abstract: | The cover of the dam site of one hydropower station is deep.The river is narrow.The proportion of river water for power is high.The reservoir sediment will soon reach the dam because of the constraint of the dam's adjusting capability,leading the problem of water diversion and sediment controlling to be big.This paper studies on the effect of cofferdam used as water diversion and sediment controlling facilities and the layout of it deeply by Hydraulic model test,comparative studying on four style of layout ... |
