摘要
考虑桥梁及堰坝的影响,建立了青川县竹园镇河道一维非恒定流数学模型,采用圣维南非稳定流偏微分方程组逐时段求解.通过"20090716"洪水对模型进行了验证,验证结果有良好的一致性.利用本模型对原设计防洪堤进行影响评估,原设计成果基本合理.基于"20090716"洪水影响,提出调整防洪标准后各防洪堤建设方案.
Considering the influence of the bridge and the weir dam, the one-dimensional unsteady flow fiver mathematical model of Zhuyuanzhen river course, Qingchuan, is built, solving by time according to Saint-Venant unsteady flow partial differential equations. The model is validated by Flood ＂20090716＂ with verified result and good consistency. It is proved that the original designed floodwall is basically reasonable by the impact evaluation with this model. The new building programs of flood control dam are also suggested in the paper, based on Flood ＂20090716＂ after the adjustment of flood control standards.
