摘　　要：利用水文学中的等流时线原理,类比自然流域地面径流的汇流过程,对城市雨水管网人工流域雨水汇流过程进行分析,得出了初期雨水弃流量在工程应用中的理论推求方法,发现现行比较常用的末端式弃流装置在雨水管网内汇流时间越长弃流效率越低,为初期雨水弃流设施设计选择提供了理论指导.Based on the principle of equal-time flow in hydrology, this paper analyzes the rainwater convergence process of artificial rainwater pipe network in urban by analogy of the convergence process of surface runoff on natural watershed. The theoretical deduction meth-od of initial rainwater discharge quantity is obtained. It provides the theoretical guidance for the design and selection of the initial rainwater split-flow equipment.
