摘　　要：随着国民经济的快速增长和汽车保有量的显著增加,现有公路的通行能力已难以满足日益增长的交通需求。公路改建拓宽工程成为解决交通拥堵、提升道路通行能力的重要手段。现依托案例工程探讨公路改建拓宽工程中的关键技术要点,包括路基拓宽处理技术、新旧工程交界面技术及交通管理等方面。选择合理的施工技术,能大幅度减少施工通病带来的质量隐患。With the rapid growth of the national economy and the significant increase in car ownership,the existing road capacity is no longer able to meet the growing transportation demand.Highway reconstruction and widening projects have become an important means to solve traffic congestion and improve road capacity.Based on case studies,this article explores the key technical points in highway reconstruction and widening projects,including roadbed widening treatment technology,interface technology between new and old projects,and traffic management.Choosing appropriate construction techniques can significantly reduce quality hazards caused by common construction problems.
