摘要
陶岔枢纽后期续建工程是南水北调中线工程的水源工程。简要介绍了该引水闸初期工程的实际运用情况,主要对后期扩建工程堆石坝加高方案引水闸的水工模型试验成果进行了阐述。内容包括水闸的泄流能力、涵洞水流流态的判别与分析、下游水流衔接及建筑物边壁压力特性等。提出了对设计方案的修改建议以及通过合理的闸门调度方式改善涵洞内水力特性的具体措施。
The extension project of Taocha Canal Headwork will be the water sources project of the Middel Line of Diversion Project from South to North China. The practical mode of opertion of the old works and, emphatically, the hydraulics test results of late extension project of the sluice, i.e.,the heightened scheme of rockfill dam, are represented,including discharge capacity,the discrimination and analyisis of flow patterns in the culvert, the conjuction of flow downstrearn and the pressure properties on the side wall of structures. Some modifications recommendations for the design and some concrete measures for improving hydraulic characteristics in culvert by reasonable gate operation are proposed.
