Application of Grouting Reinforcement Treatment Technologyin Subgrade Construction of Expressway

为研究注浆加固处理技术在高速公路路基施工中的应用,改善路基不均匀沉陷变形问题,论文结合实际工程,分别对路基沉陷病害以及注浆加固机理进行阐述,并重点对注浆加固施工技术要点进行分析。研究结果表明,采用注浆加固技术可有效缓解及改善路基沉陷病害问题,同时能预防路基不均匀沉降变形的发生,并可提高路基的整体平整性。

In order to study the application of grouting reinforcement treatment technology in the construction of expressway subgrade,improve the problem of uneven subgrade subsidence and deformation,combined with practical engineering,this paper elaborates the roadbed subsidence diseases and grouting reinforcement mechanism,focuses on the analysis of grouting reinforcement construction technology key points.The research results show that the grouting reinforcement technology can effectively ease and improve the roadbed subsidence disease problem,at the same time,it can prevent the happening of the roadbed uneven settlement deformation,and improve the overall smoothness of roadbed.
