Research and Practice of Road Engineering Design Based on Sponge City Design Concept
In order to solve the problems of waterlogging and drought caused by poor drainage systems in cities,the design concept of sponge cities is introduced in the design process.Firstly,based on the introduction of the basic concept of sponge city,the basic situation of engi-neering projects,the current situation of the site,and the prediction of traffic volume,an overall plan for sponge city design is pro-posed.According to the basic design requirements and technical principles of sponge city,design and research are conducted on key design nodes such as road engineering plane design,longitudinal section design,cross-sectional design,and rainwater engineering.According to the research results,it can be concluded that the large drainage system,small drainage system,and micro drainage system adopted in this project meet the construction requirements of sponge cities.
