摘　　要：饶河双港—褚溪河口航道整治工程实施后,遭遇2022年极端枯水条件下,局部存在碍航浅滩段。依据实测资料及数学模型计算,对浅滩演变、基本站设计水位变化及最低通航水位进行计算分析。结果表明,工程后朱袍山—褚溪河口段航槽深泓高程以下降为主,平均值为0.7~3.0 m,冲刷总量为137.31万m^(3);延长水文系列至2021年,饶河双港下游段基本站设计最低通航水位下降值为0.12~0.61 m;设计最低通航流量条件下,饶河湖区段水位下降最大值为0.13~0.25 m,平均为0.05~0.11 m。After the channel regulation from Shuanggang to Chuxi estuary of Raohe River,there are some shallow sections obstructing navigation in extremely low water conditions in 2022.Based on the measured data and mathematical model calculation,this paper calculates and analyzes shoal evolution,designed water level changes of the basic station,and the lowest navigable water level.The results show that the navigation channel from Zhupaoshan to Chuxi estuary is mainly cut down,with an average value of 0.7-3.0 m and a total scouring volume of 1.3731×106 m^(3).Meanwhile,the hydrological series are extended to 2021,and the designed water level drop of the basic station will be 0.12-0.61 m.Under the designed lowest navigable flow,the maximum water level decline in lake reach of Raohe channel is 0.13-0.25 m,with an average of 0.05-0.11 m.
