摘　　要：沿海地区深厚软土地基处理一直是工程界的难点,以中山至开平高速公路为依托采用大直径管材代填路基填料,经有限元数值模拟计算,分析了施工过程中的累积变形、沉降及其分布规律,并与施工过程中的实测数据对比,满足规范要求,为软基处理提供新思路。The treatment of deep soft soil foundation in coastal areas has always been a difficulty in the engineering field.Relying on Zhongshan-Kaiping expressway,large-diameter pipe material is used to fill the subgrade filler.Through finite element numerical simulation calculation,the cumulative deformation,settlement and its distribution law during the construction are analyzed and compared with the measured data during the construction,which can meet the code requirements,and provide a new idea for soft foundation treatment.
