融入公园城市理念的城市街道一体化研究

Research on Integration of Urban Streets Incorporating Concept of Park City: A Case Study of Chengluo Expressway Reconstruction in Chengdu

摘要:

为践行公园城市理念、解决成洛路现状问题并推动城市道路高质量发展，以成都市成洛快速路改建项目为工程实例，开展城市街道一体化设计研究。基于实地调研与多源数据分析，提出安全高效、生态优先、功能复合、人文彰显、以人为本5大核心设计原则，通过分段横断面优化、路面结构优化、交叉口渠化改造、市政基础设施一体化设计，以及基于分段分类方法的景观与道路协同设计，形成系统性改造方案。实践表明，该方案有效提升了道路通行效率、生态环境品质与文化活力，实现了交通功能、生态环境、城市空间与地域文化的有机融合，为类似城市快速路改建项目提供了可借鉴的一体化设计范式。

Abstract:

To implement the concept of a park city, solve the current problems of Chengluo Road and promote the high-quality development of urban roads, and taking the Chengdu Chengluo Expressway Reconstruction Project as an example, the integration design of urban streets is studied. Based on the field researches and multi-source data analysis, five core principles of security and efficiency, ecology priority, functional integration, humanistic highlighting, and people orientation are proposed. A scheme of systematic reconstruction is formed through optimization of segmented cross-sections, optimization of pavement structure, channelized reconstruction of intersections and integrated design of municipal infrastructure, and landscape-road collaborative design based on segmented classification methods. The practices show that this scheme effectively enhances the traffic efficiency, ecological environmental quality and culture vitality of the road, and achieves the organic integration of traffic function, ecological environment, urban space and regional culture, providing a referenceable integrated design paradigm for similar urban expressway reconstruction projects.
