城市道路提升改造设计的探索与实践

Exploration and practice of urban road upgrading design

城市道路提升改造具有现状条件复杂,专业交叉、新旧不一、施工环境恶劣等特点,随着城市道路建设的高速发展,新建道路日趋饱和,既有道路运营维护期间,无法避免地存在翻修改建等技术问题。如何对既有城市道路进行改造提升,保证改善其交通功能、延长使用寿命,是城市基础设施建设者应当关注的焦点。研究以福建省南平市松溪县一城市主干路提升改造工程为背景,结合项目的工程特点,分析探讨城市旧路提升改造中需要建设的主要内容及注意事项,通过优化设计,全面提升道路使用功能和使用年限,可为类似道路改造工程设计提供参考借鉴。

Urban road upgrading has the characteristics of complex current conditions,professional intersection,different old and new,bad construction environment and so on.With the rapid development of urban road construction,new roads are increasingly saturated.During the operation and maintenance of existing roads,there are inevitable technical problems such as renovation and reconstruction.How to upgrade the existing urban roads to ensure the improvement of their traffic function and prolong their service life is the focus of urban infrastructure builders.Study in fujian nanping songxi county city distance increase reconstruction project as the background,combined with the engineering characteristics of the project,analysis to investigate the city the main content of the need to build in the old road promotion transformation and the matters needing attention,through the optimization design,improve road use function and use fixed number of year,and can provide a reference for similar road reconstruction project design.
