摘　　要：城镇密集区低等级公路严重影响公路运输效率,需合理改扩建现有道路。通过分析城镇密集区道路改扩建工程的交通特性、交通组织原则和流程,结合工程实例,深入分析交通组织,在分析路段及改扩建项目特点的基础上,结合路段限制条件,对不同里程段分别提出单侧扩宽、双侧扩宽施工方案,给出路基与路面关键施工技术,并提出相应的交通组织方案和安全保障措施,确保道路改扩建工程顺利实施,取得良好施工效果。The low-grade highway in the urban dense area seriously affects transportation efficiency,so it is necessary to reconstruct and expand the existing road.Based on the analysis of the traffic characteristics,traffic organization principles and processes of the reconstruction and expansion projects in the urban dense areas,combined with the engineering examples,the traffic organization is analyzed deeply.On the basis of the analysis of the road sections and its characteristics,combined with the restrictions of the road sections,the unilateral and bilateral widening of different mileage sections are proposed respectively.The traffic organization scheme and safety guarantee measures are put forward to ensure the smooth implementation and achieves good construction results.
