摘要
传统的城市道路设计方法往往存在排洪压力大、雨水资源流失、破坏生态等问题,容易造成城市暴雨积涝灾害,海绵城市理念可以有效解决这一问题。鉴于此,本文首先分析了目前城市道路排水设计中存在的问题,随后以某城市道路为研究对象,探讨了海绵城市理念在路面结构优化设计、植草沟设计、排水管网优化等中的应用,最后利用SWMM模型对海绵城市道路的排水效果进行了评价,以期为市政道路设计提供一定的理论指导。
Traditional urban road design methods often have problems of high flood discharge pressure,loss of rain water resources,and destruction of ecology,which are easy to cause urban rainstorms and flood disasters.The concept of sponge city can effectively solve this problem.In view of this,this paper first analyzes the problems in the current urban road drainage design,and then uses a city road as a research object to discuss the application of the sponge city concept in pavement structure optimization design,grass planting trench design,drainage pipe network optimization,Finally,the SWMM model was used to evaluate the drainage effect of sponge city roads,with a view to providing a certain theoretical guidance for the design of municipal roads.
