摘　　要：黄河干流宁夏中卫市康滩—营盘滩河段长约9 km,平面宽窄相间,呈藕节状。针对康滩—营盘滩河段河道弯曲、支汊纵横、航槽不明、流态紊乱等问题,采用河工模型试验对疏浚浅区、拓宽航槽的航道整治效果进行分析,并根据试验结果对设计方案进行优化。最终确定中宁大桥滩采用新开航槽弯曲半径大于550 m,与上、下游航道平顺衔接,太平滩采用疏浚、筑坝和填槽相结合的整治措施,能够有效改善通航水流条件,保障通航安全。The river reaches from Kangtan to Yingpantan in Zhongwei of Ningxia,the mainstream of the Yellow River,is about 9 km long,wide and narrow in plan,and has the shape of a lotus root joint.Considering the problems of channel curvature,bifurcations,unknown channel,violent turbulence in the river reaches from Kangtan to Yingpantan,we use the river model test to analyze and research the effect of channel regulation by dredging the shallow area and widening the channel,and optimize the design scheme according to the test results.It is found that the bending radius of the newly opened fairway at Zhongning Bridge beach is more than 550 m and the upstream and downstream fairways are smoothly connected with each other,and at Taiping beach,the rehabilitation measures of dredging,impoundment and slot filling are carried out,which can effectively improve the flow conditions and ensure the safety of navigation.
