| 摘 要： | 为结合分析一维河模型和二维洪泛区模型,利用InfoWorks RS对蒋巷联圩防洪保护区洪水演进过程进行二维模拟,分别选取2010年和1998年外洲水文站实测资料对一维河道模型进行了率定和验证,结果较为合理;选取赣江50 a一遇设计洪水同时鄱阳湖遭遇湖口22.5 m(吴淞高程)恒定洪水位的边界条件,分析了最不利工况下区内的溃口溃决过程、洪水演进过程及淹没水深等要素,计算结果较好地反映了区内溃堤后的洪水演进情况。研究成果可为江西省防洪减灾提供决策支持。

| Abstract: | InfoWorks RS was adopted to simulate the 2D flood routing at Jiangxiang Dike by combining 1D channel model and 2D flooded area model, and the water depth, flow velocity, arrival time and other factors in the flood protection area under the most unfavorable conditions were analyzed. The measured water level data in 2010 and 1998 were used to calibrate the model, and the results indicated that the model is reasonable. The boundary conditions used in the model was 50-year event flood in Ganjiang River combined with constant flood level 22.5 m(Wusong elevation) at Hukou Station. The results demonstrate that the model could reflect the flood routing process well after dike breaking. This research offers technical support for the disaster reduction of Jiangxi province. |
