摘　　要：介绍了丹江口大坝加高后的水力学模型研究成果,含枢纽泄流能力、溢流坝面及门槽边壁压力特性以及坝下河床冲刷等,并与大坝加高前已运行30余年的原型观测资料进行了对比,分析了其合理性和可靠性,对存在的问题亦提出了改进措施。This paper introduces the hydraulics test results on the heightened scheme of Danjiangkou Dam, including discharge capacity,pressure characteristics of the spillway surface and in gate slots region, scouring situation of the riverbed downstream dam, etc.. By comparing the test results with prototype observation data from the existing dam, which has run for over thirty years, their rationality and reliability are analyzed, and the improvement measures for solving existing problems were proposed.
