摘要
国民经济快速增长,使得各地区区域间交流变得更加频繁,高速公路交通量呈现出了明显上升的趋势,原有高速公路已经无法满足现代交通实际需求,需要进行改建以及扩建施工。文章将以江西昌樟高速公路改扩建项目为例,对高速公路改扩建新老路基差异变形和路基拓宽施工工艺展开全面论述,旨在明确新老路基差易变形有效处理方式,提升国内路基拓宽工艺施工水平。
With the rapid growth of the national economy, the regional communication has become more frequent, and the traffic volume of the highway has showna clear upward trend. The original highway has been unable to meet the actual needs of modern traffic. Alterations and extensions are required. Taking the reconstruction and extension project of Chang-Zhang Expressway inJiangxi Province as an exemplar, this paper discusses comprehensively the differential deformation of new and old roadbed and theconstruction technology of roadbed widening, in order to clarify the effective treatment method for the difference of new and oldroadbed and improve the construction level of roadbed widening technology in China.
