高等级公路拓宽改造质量控制技术

Quality control technology for highway widening and reconstruction

结合国内相关工程实例,分析总结了旧路基加宽地基处治措施,提出了新旧路基衔接技术,归纳总结了新旧路基结合部施工工艺标准,对旧路基拓宽改造质量控制具有实际意义。

Combining with the relevant successful engineering examples in China,this paper summarizes the treatment measures for widening the foundation of the old roadbed,puts forward the connection technology between the new and the old roadbed,summarizes the construction technology standards for the joint of the new and the old roadbed,which has practical significance for the quality control of the widening and transformation of the old roadbed.
