中文摘要:
      由于工程取水需求,拟在官渡河上修建一座泵站引水工程。为寻求最优取水布置方案,通过物理模型试验对官渡河取水工程布置方式进行验证。结果表明,当溢流坝为弧形时,在10年一遇洪水条件下,取水工程上游来水来沙量较大,冲沙闸前出现大量泥沙淤积,取水口门前也存在泥沙淤堵现象;将溢流坝由弧线形调整为直线形布置后,其防沙效果得到明显改善,改进后的方案对弯道取水工程布置,原则上不改变原有弯道水沙输移特性,即可充分利用弯道环流达到安全取水目的。研究结果可为类似弯道取水工程布置设计提供参考。
英文摘要:
      In order to satisfy the cooling water needs of Tongzilin project, a pumping station diversion project will be built on the Guandu river. In this paper, physical model test of Guandu river project was carried out to seek the optimal solution for water intaking. The test results show that a mass of sediment deposit in the gateway of diversion headwork with much water and sediment comes from the upstream under the once in decade condition when the overflow dam is arc shaped. After changing the arc shaped overflow dam into linear arrangement, optimization plan had good effect and the gateway of diversion headwork did not deposit sediment any more. The arrangement of diversion project in meandering river does not change the specialty of flow and sediment transport circumfluence in the original meandering river, which will guarantee the safety of water intaking from the meandering river. The conclusion has some reference for similar projects.
