设计降雨雨型是排水管网水力模型法计算的先决条件，其峰值系数是影响管网的设计流量的重要因素，直接决定了管网的设计规模及工程造价。该文借助 InfoWorks ICM水力模型软件，以广州市某实际片区排水管网工程设计为例，定量分析设计降雨雨峰系数对管网设计流量的影响程度，并给出雨峰系数的确定方法，对于设计降雨在水力模型中的正确应用具有示范效应。

Design rainfall hydrograph is the prerequisite for calculation of drainage pipe network hydraulic model method. Its peak value is an important factor to affect the design flow of pipe network and directly determines the size of pipe network and project cost. In this paper,with the help of InfoWorks ICM software,on the basis of a practical area of drainage pipe network design in Guangzhou city,the quantitative analysis of influence of design rainfall peak coefficient on design flow of pipeline network was analyzed,and the rain peak coefficient was determined,which has a demonstration effect on correct application design in hydraulic model of rainfall.
