| 摘 要： | 以长江口高桥站为研究对象，根据历史资料，用经验分析和统计结合起来的方法，建立风暴潮增水模式，依据流体动力学原理建立二维风暴潮天文潮综合水位模式，尔后以极值气象因子为基础，利用因子组合法及台风位移法分别设计极端台风模型，推算高桥站最大增水及可能最高潮位，并以水文统计频率分析成果作为研究确定长江口ＰＭＴ的佐证。

| Abstract: | Taking the Gaoqiao hydrological station as a study object, based on the practical data and using themethod of statistics and relation analysis,this paper sets up several storm surge increment models, and 2-D coupling numerical models of the storm surge and astronomical tide at the Yangtze River Estuary,accortling to the hydrodynamics theory. After designing the patterns of the extreme typhoons affecting possibly the estuary by themethod of the effecting factors combination and typhoon displacement,the maximun increment and highest tidal levelare calculated.Finally,this study has given a PMT of the extuary in the near future. |
