摘　　要：为分析向家坝水电站日调节运行对下游中嘴码头通航水流条件的影响,建立1:100正态物理模型,对向家坝水电站典型日调节工况进行模拟,分析日调节非恒定流引起的中嘴码头水域流速、水位和比降等通航水力要素的变化过程,同时结合流场分布资料和自航船模试验,研究日调节对船舶航行以及进出港靠泊的影响。结果表明,电站按照拟定的水位变幅进行日调节时,码头河段水位变幅未超过电站运行调度规程允许值,水流条件满足船舶航行要求,船舶可以正常进出港靠泊作业,对码头运行影响较小。研究成果可为电站日调节调度运行提供参考。To analyze the influence of daily regulation operation of Xiangjiaba Hydropower Station on the navigable flow conditions of downstream Zhongzui Wharf,a 1100 normal physical model is established to simulate the typical daily regulation operation of Xiangjiaba Hydropower Station,and the change process of navigable hydraulic factors such as velocity,water level and gradient of the water area of Zhongzui Wharf caused by daily regulation unsteady flow is analyzed.At the same time,combining the flow field distribution data and self-propelled ship model test,the influence of daily regulation on ship navigation and berthing in and out of the port is studied.The results show that when the power station conducts daily regulation according to the proposed water level variation,the water level variation of the wharf reach does not exceed the allowable value of the power station operation regulation,the flow conditions meet the requirements of ship navigation,and the ships can normally enter and leave the port for berthing operation,with little impact on the wharf operation.The research results can provide reference for daily regulation and operation of power stations.
