高速公路路基施工技术及质量控制分析

Analysis on Construction Technology and Control Points of Expressway Subgrade

路基是公路结构的主体也是路面的直接承载体,保障公路整体结构的稳定性及路面行驶的安全性,其施工质量是整个公路工程质量的关键,必须严格控制。以广东某新建高速为例,简述路基施工特点及要求,并针对施工过程中路基开挖、填筑、压实、排水等环节的施工技术及质量控制要点进行分析和探讨,为进一步优化和改进路基施工技术提供参考和依据。

The roadbed is the main body of the road and the direct bearing body of the pavement structure.It guarantees the overall stability of the highway and the safety of the road.Its construction quality is the key of the whole highway project and must be strictly controlled.Taking a highway in Guangdong as an example,this paper briefly describes the characteristics and requirements of roadbed construction,and probes into and analyses the construction technology and quality control points of roadbed excavation,filling,compaction,drainage and other links in the construction process,so as to provide reference and basis for further optimization and improvement of roadbed construction technology.
