海绵城市建设中城市道路雨水系统设计分析

Design and Analysis of Urban Road Rainwater System in Sponge City Construction

随着城市规模的不断扩大,城市原有的水文条件得到了极大的改变,一定程度上降低了雨水的下渗和蒸发,增加了城市地表的径流,城市内涝和地下水污染问题日渐严重。为了适应环境的变化,提高城市应对自然灾害的能力,海绵城市的应用日渐广泛。和传统的雨水排放系统相比,海绵城市的道路雨水系统可以实现对雨水径流的有效控制,降低了城市内涝问题的产生几率,有效地保护了城市的生态环境。本文简单介绍海绵城市的概念,分析研究海绵城市建设中城市道路雨水系统设计,为相关工作者提供参考借鉴。

With the continuous expansion of the city scale,the original hydrological conditions of the city have been greatly changed,to a certain extent,reducing the infiltration and evaporation of rainwater,increasing the ur- ban surface runoff,urban waterlogging and groundwater pollution is becoming increasingly serious.In order to adapt to changes in the environment and improve the ability of cities to deal with natural disasters,sponge cities are increasingly widely used.Compared with the traditional rainwater drainage system,the road rainwater system in sponge city can effectively control the rainwater runoff,reduce the probability of urban waterlogging problems, and effectively protect the ecological environment of the city.This paper briefly introduces the concept of sponge city,analyzes and studies the design of urban road rainwater system in the construction of sponge city,and pro- vides reference for relevant workers.
