中文摘要：

解决基于Saint-Venant方程组的传递函数模型的问题,应用于城市排水系统合流管道污水溢出的控制,使溢出率最小。利用现存的排水系统设施,通过灵活的控制和最优化流量以达溢出率最小的目的。首先,基于Saint-Venant方程组,推导出应用于排水管道的一般的传递函数模型;然后,对于中间有旁侧流入的一段两节点的排水管道进一步分析,基于上面的模型进行计算;最后,应用MIKEURBAN软件进行仿真,与模型计算的结果进行比较分析。

英文摘要：

Problem in this paper is based on the Saint-Venant equations of the transfer function model.It was applied to urban drainage systems combined sewage overflow control to minimize spillover rate.Using the existing drainage system facilities,through flexible traffic control and optimization,the purpose of the smallest overflow ratio is achieved.Firstly,the general transfer function model used in drain pipes is derived based on Saint-Venant equations.Then,for the middle section of two flanking the node into the drains is further analysed,based on the above model calculation. Finally,MIKEURBAN software is applied to simulate,and a comparative analysis of the results between the model and the software is achieved.
