濒湖（河）段软基因冲积相成因的淤泥质土物理力学性质极差，难以满足高速公路路基承载力和沉降的要求，通常需使用振动水泥碎石桩对地基进行处理。文中结合德兴—南昌高速公路新建工程 K133＋850～K134＋050段软基处理实例，介绍振动水泥碎石桩的使用依据及施工工艺，并阐述水泥碎石桩处理此类软土地基的有效性。

Due to the poor physical and mechanical properties of silt soil near lake (river)range soil o-riginated from alluvial faces,it is generally difficult to meet the requirements of bearing capacity and settlement of highway subgrade.The general case requires the use of vibration gravel pile for founda-tion treatment of cement.In this paper,combined with the Dexing-new examples of Nanchang expre-ssway soft foundation treatment K133+850~K134+050 project,the use of foundation and construc-tion technology of vibrating cement gravel pile is introduced,and the validity of this kind of soft soil foundation treatment of cement gravel pile is explained.
