摘　　要：使用有限元软件ADINA对柔性基础下夯实水泥土楔形桩复合地基和夯实水泥土圆柱形桩复合地基的变形规律做了初步的数值模拟分析,得出了在各级荷载作用下软基的侧向、竖向变形基本规律并对它们进行了对比,认为用楔形桩加固软基是经济的、安全的。The deformation laws both of the rammed soil-cement tapered pile composite foundation and the rammed soil--cement cylindrical pile composite ground under flexible foundation was simulated by means of finite element software ADINA, in which the horizontal deformation and vertical deformation was obtained. Then through comparing results, it＇s the tapered pile composite foundation to reinforce the soft foundation that is economy and security.
