摘要
软土具有含水量高、孔隙比大、强度低、压缩性高等特点,导致修建在深层软土地基上的道路存在路基失稳、工后沉降大的问题,因此对深层软土地基的路基处理关乎工程成败,是道路建设中的一个重要问题。文中通过分析现有的常用软土路基处理方法后,认为CFG桩复合地基具有稳定性好、施工简便、承载力高、工程沉降控制方面更有优势,有较好的应用价值。
Soft soil has the characteristics of high water content,large void ratio,low strength and high compressibility,which leads to the problems of subgrade instability and large post construction settlement of the road built on deep soft soil foundation.Therefore,the subgrade treatment of deep soft soil foundation is related to the success or failure of the project and is an important issue in road construction.After analyzing the existing common soft soil subgrade treatment methods,it is considered that CFG pile composite foundation has good stability,simple construction,high bearing capacity,more advantages in engineering settlement control,and has better application value.
