基于海绵城市设计理念的道路工程设计研究与实践

Research and Practice of Road Engineering Design Based on Sponge City Design Concept

为了解决城市因排水系统不良引起的内涝和干旱等问题,在设计过程中引入海绵城市的设计理念。首先,在分析介绍海绵城市的基本概念、工程项目的基本情况、现场现状和交通量预测的基础上,提出海绵城市设计的总体方案。根据海绵城市的基本设计要求和技术原则,针对道路工程的平面设计、纵断面设计、横断面设计和雨水工程等关键设计节点进行设计研究。通过研究可知,本项目采用的大排水系统、小排水系统和微排水系统,符合海绵城市的建设要求。

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 engineering projects,the current situation of the site,and the prediction of traffic volume,an overall plan for sponge city design is proposed.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.
