摘　　要：伴随着城市现代化进程,城市内涝问题日益突出,我国大部分城市都发生过城市内涝。而专家学者和民众对内涝的认识却存在一定的偏差,很多人没有认识到内涝是由降雨积水发展到一定程度而产生的,把积水和内涝等同。本文基于InfoWorks ICM软件构建了城市道路降雨径流模型,模拟了不同坡度以及不同重现期降雨情况下的道路积水发展过程,阐明了地面积水深度的变化规律和积水与内涝的关系。可帮助人们对于积水内涝过程的理解,也有利于有关部门进行内涝防治工作。Along with the process of urban modernization,the problem of urban waterlogging is becoming more and more serious.Most cities in China have experienced urban waterlogging.However,experts,scholars and the public have certain deviations in their understanding of waterlogging.Many people do not realize that waterlogging is caused by the development of rainfall and waterlogging to a certain extent,and waterlogging is not equal to waterlogging.Based on the InfoWorks ICM software,a rainfall-runoff model of urban roads was constructed to simulate the development process of road waterlogging under different slopes and different return periods of rainfall,and to clarify the variation rule of waterlogging depth.It can help people to understand the process of waterlogging,and also help relevant departments to carry out waterlogging prevention work.
