| 摘 要： | 为探讨山区河流库尾河段航道整治技术,以嘉陵江南充段凤仪场库尾河段为例,分析河床演变、滩险及泥沙淤积规律,探明河段的碍航特性。采用河工模型试验方法,制定了"疏浚、筑坝、护岸"等整治方案。试验表明:优化方案实施后整治效果良好,从根本上解决了山区河流库尾河段变动回水区碍航问题。

| Abstract: | To discuss the waterway regulation technology of the tail reach of mountainous rivers,we analyze the riverbed evolution,beach risk and sediment deposition law by taking the tail reach of Fengyi yard in Nanchong section of the Jialing River as an example,and get to know the navigation-obstructing characteristics of the reach. Adopting the river model test method,we make the regulation scheme for the dredging,damming and revetment.The test results show that the regulation effect is favorable by the implementation of the optimization scheme,which solves the navigation-obstructing problem fundamentally in the fluctuating backwater area of the tail reach of the mountainous rivers. |
