| 摘 要： | 金沙江最下游梯级向家坝水电站,因其装机容量大,发电运行期间非恒定流造成坝下水位日变幅及小时变幅较大,会对长江叙渝段航道维护造成严重影响。基于长河段非恒定流数学模型,研究向家坝水电站日调节运行后长江上游非恒定流传播特性,分析日调节运行对航道维护的影响,提出相应航道维护管理对策。

| Abstract: | Xiangjiaba hydropower station in the Jinsha river has a big installed capacity.During operating,it will cause downstream unsteady flow which makes the big water level variation amplitude,and thus influence seriously the waterway maintenance management of Yibin to Chongqing reach of the Yangtze River. Based on the long river unsteady flow mathematical model,we study the development of the unsteady flow,analyze the influence of the daily regulation of waterway maintenance,and put forward corresponding maintenance management measures. |

| Keywords: | daily regulation unsteady flow waterway maintenance river reach from Yibin to Chongqing |
