【摘要】 尾水壅水堰是电站尾水位下降整治中一种全新的工程措施。根据模型试验观测结果,研究了在闽江水口水电站尾水渠修建壅水堰后尾水渠水位变化及近坝河段的水流条件变化。结合地形、地貌、尾水渠的特点对原方案堰轴线进行旋转得到了3个修改方案并进行了优化,其模型试验结果分析表明:优化方案的各项水力要素满足工程要求。更多还原

【Abstract】 Backwater weir is an absolutely new engineering measure which can regulate the tail water level in the power station tailrace.The tailrace water level change in the Minjiang Shuikou power station tailrace after the construction of the tail water backwater weir and the flowing conditions change near the dam tailrace are studied by the hydraulic model tests.Combining with topography and the characteristics of the tailrace,the weir axis of the original scheme is rotated to obtain 3 amending proposals and then the 3 proposals are optimized.The model test results show that various hydraulic elements of the optimization program meet the engineering requirements.更多还原
