摘要
以历城区柳埠镇所在3个小流域为研究对象,选用MIKE11模拟软件建立了一维河道沿程洪水演进模型[1],完成了不同量级洪水的演进过程模拟与分析。拟定了五种不同的洪水模拟方案,并对不同设计方案下的洪水的演进过程进行了模拟,得出了不同量级洪水沿程水面线动态结果、各断面洪峰流量及淹没水位结果和各断面淹没水深结果。结果表明:模型对山丘区小流域洪水演进过程整体模拟效果可信,可应用于实际山丘区小流域的预警指标的计算分析中;模型模拟结果符合河道洪水演进规律,可为该地区防洪评价及预警工作提供一定的数据支撑和参考依据。
In this paper,three small watersheds of Liubu Town are selected as the research object,and the model of flood submerging simulation is established by using MIKE 11 software. It has completed the flood submerging simulation and analysis of different flood magnitude.The five simulation schemes are determined. And then the model is used to simulate the flood submerging process under the five modes. The flood inundation results including submerged water surface line of different magnitude,the flood peak flow,submerged water level and submerged water depth are obtained.The main conclusions are as follows: all parameters meet the accuracy requirements,which can be used for further modeling. The model simulation results accord with the law of river flood evolution. It can provide a data support and reference basis for the flood control evaluation and early warning in this area.
