摘　　要：浦阳江航道水位既受到上游径流洪峰流量的影响,又受到下游潮水顶托,高水位成因复杂。为加强航道和桥梁等涉航建筑物的管理,进一步提升浦阳江航道通行能力,迫切需要对浦阳江航道进行通航水位论证。根据《内河通航标准》中的各级洪水重现期的水位采用设计流量法推求设计最高通航水位的方法,通过建立二维水动力数学模型,模拟计算5 a、3 a及2 a洪水重现期工况下的沿程水位。考虑浦阳江河道状况、航道等级、水流条件和桥梁通航净空等条件,结合上下游河段设计水位、防汛特征水位、历时水位统计等资料,经综合分析,推荐浦阳江2 a洪水重现期水位作为设计最高通航水位。The stage of the Puyang River waterway is not only influenced by the runoff peak discharge in the upstream regions,but also supported by the tidal water in the downstream regions.Thus,the reasons for the high stage are complex.It is very urgent to demonstrate the navigable stage of the waterway for strengthening the management of navigation-related structures such as navigation channels and bridges and further enhancing the capacity of the waterway.In the Navigation Standard of Inland Waterway,the designed highest navigable stage is deduced by the design flow method with the stages in flood recurrence periods at different levels.In light of this,we establish a two-dimensional hydrodynamic mathematical model to calculate the designed highest navigable stage for 5-year,3-year and 2-year flood recurrence periods.Taking into account the river channel conditions,channel grades,flow conditions and bridge’s navigation clearance,we recommend the stage of Puyang River in the 2-year flood recurrence period as the highest designed navigable stage by referring to the data of designed stages upstream and downstream,characteristic stage under flood control and historical stage statistics.
