南方山区公路路基施工关键技术及研究

Key Technology and Research on Highway Subgrade Construction in Southern Mountainous Area

施工技术是路基施工的重要内容,而路基压实、边坡设置、排水系统的优劣则是保证整体施工质量的关键点,对公路质量及使用寿命有很大的影响。根据山区特有的施工环境分析了控制边坡稳定性的因素及水对路基压实、边坡稳定性的影响及排水设施在施工中的重要作用,从影响因素对路基稳定性之间的关系出发阐述了路堤、路堑施工中填压、开挖、排水、边坡设置等关键技术。

Construction technology is an important part of subgrade construction.The compaction of subgrade,setting of slope and drainage system are the key points to guarantee the overall construction quality,which have a great influence on the quality and service life of highway.According to the unique construction environment in mountainous areas,this paper analyses the factors controlling the stability of slope,the influence of water on the compaction of subgrade,the stability of slope and the important role of drainage facilities in construction.Starting from the relationship between influencing factors and subgrade stability,this paper elaborates key technologies such as filling,excavation,drainage and slope setting in embankment and cut construction.
