基于海绵城市理念的道路提升改造设计与实践

Design and Practice of Road Improvement and Reconstruction Based on Concept of Sponge City

摘要:

在城市化进程加速与生态环境压力凸显的双重背景下，海绵城市理念为道路工程设计提供了全新的生态化转型路径。作为城市下垫面的重要组成部分，道路的传统硬化设计模式是导致城市内涝、雨水资源浪费和生态功能退化的关键因素。结合天安路改造提升工程、兴宁北路改造提升工程两大工程实践案例，提出海绵城市理念在道路工程中的融合路径和关键技术，分析实践成效。通过三维效益评价分析，融合海绵城市理念的道路工程将成为推动城市可持续发展的重要支撑。

Abstract:

Against the dual backdrop of accelerated urbanization and prominent ecological environmental pressures, the concept of sponge city provides a new path for ecological transformation in road engineering design. As an important component of the urban underlying surface, the traditional hardened design model of roads is a key factor leading to urban waterlogging, waste of rainwater resources, and degradation of ecological functions. Combined with two practical engineering cases, namely the Tian'an Road Reconstruction and Improvement Project and the North Xingning Road Reconstruction and Improvement Project, the integration path, key technologies and practical achievements of the sponge city concept in road engineering are proposed. Through three-dimensional benefit evaluation and analysis, the road projects integrating the concept of sponge cities will become an important support in promoting the urban sustainable development.
