高速公路施工中软土路基施工关键技术研究

Research on key technologies of soft soil roadbed construction in expressway construction

随着我国经济高速发展,高速公路工程也得到了长足发展。软土路基因其含水量高、渗水性差、承载能力弱等特征,施工中极易发生不均匀沉降和承载力损失等问题,对施工质量与经济效益造成严重影响,因此针对软土路基制定针对性处理方案是十分必要的。本文对高速公路施工中软土路基施工关键技术进行了研究,主要针对软土路基处理、路基排水与路基填筑三个方面,研究并总结了施工流程及施工关键技术,对施工中可能存在的问题制定了相应处理措施,最大限度减少了软土路基施工不良影响,保障了施工质量与经济效益。

This article studies the key technologies of soft soil roadbed construction in highway construction,mainly focusing on three aspects:soft soil roadbed treatment,roadbed drainage,and roadbed fi lling.The construction process and key technologies are studied and summarized,and corresponding treatment measures are formulated for possible problems during construction,minimizing the adverse effects of soft soil roadbed construction and ensuring construction quality and economic benefi ts.
