对市政老路的改建是许多城市进行交通改善及路网结构调整的重要手段之一。以山西省忻州市七一路老路改建工程为例,探讨老路改建工程中的设计原则,关注在老路改建过程中改造技术、现状情况和经济指标等各要素相互间平衡的关键。契合可持续发展的基调,强调了拆迁、环境、绿化、造价等因素与工程的突出矛盾,通过对工程实例的研究,探讨这些因素在其中所发挥的作用。
The rebuilding of the old municipal road is one of the important means for traffic improvement and road network structure adjustment in many cities. Taking the reconstruction of old road in Qiyi Road, Xinzhou City, Shanxi Province as an example, this paper discusses the design principles in the reconstruction of old roads, and focuses on the key points of balancing the various elements of transformation technology, status quo and economic indicators during the reconstruction of old roads. In line with the keynote of sustainable development, the prominent contradictions between demolition, environment, afforestation, construction cost and other factors and engineering are emphasized. Through the study of engineering practice, the role played by these factors is explored.
