摘　　要：在传统的城市排水管网设计和管理中一般采用恒定均匀流进行水力计算,无法进行管道内有压流状态和无压流状态之间的计算衔接,而水力模型采用非恒定非均匀流能模拟计算管道内部的真实流态。将水力模型应用于北京市北土城沟流域雨水系统研究中,建立雨水系统(从降雨、径流、管网收集到河道排除)评价体系,模拟流域内积水的全过程,优化流域内河道闸门的调度方案,为今后建立城市防汛应急预警系统、城市雨水系统科学管理起到探索作用。In traditional municipal drainage network design and management,the steady uniform flow is usually employed in hydraulic calculation,so the calculation connection between pressure flow and free surface flow in the pipe can＇t be carried out.In the hydraulic model,the unsteady uniform flow is employed to simulate the real flow inside the pipe.In this paper,the hydraulic model is applied in the Beijing Beitucheng trench basin storm water system study to set up the storm water system（from rainfall,rain flow runoff,pipe network collection to river drainage） evaluation system,simulate the entire process of basin storm waterlogging,and optimize the management of the basin river gates,which can be references for the establishment of urban flood emergency plan,municipal runoff systematic management.
