城市道路大修工程的精细化设计

Fine Design of Urban Road Overhaul Engineering

随着城市化建设的快速发展,城市道路设施规模急剧增长,越来越多的城市道路已接近或超过设计使用年限,进入大修养护期。相对于一般新建道路工程,城市道路大修具有工期短、不中断交通施工、与市政管线及周边建筑设施联系密切、控制因素多等特点,需要设计考虑的内容较多,是一项十分细致、复杂而又极其灵活的工作。因此,城市道路大修工程迫切需要进行精细化地设计。特别是"人文交通、科技交通、绿色交通"的新北京交通体系建设,对城市道路大修工程的设计提出了更高要求。该文详细地阐述了城市道路大修工程的精细化设计理念,并结合"长安街道路大修工程"和"前三门道路大修工程"等工程实例,对精细化设计理念的理解,精细化设计内容及细节处理措施等进行了系统的论述,对提升城市道路大修工程精细化设计水平,提高城市道路大修工程质量有着积极的意义。

With the fast development of urbanization construction, the scale of urban road facilities sharply increases. More and more urban roads have been close to or exceed the design service life into the overhaul period. The article sets forth the fine design idea of urban road overhaul engineering in detail. According to the engineering cases of Chang’an Avenue Road Overhaul Project and Qiansanmen Road Overhaul Project, and understanding the fine design idea, the article systematically discusses the fine design contents and the detail treatment measures, which has the active significance for enhancing the fine design level of urban road overhaul engineering and enhancing the quality of urban road overhaul engineering.
