| 摘 要： | 基于长桩侧向约束作用,利用大型有限元软件ADINA,对柔性基础下夯实水泥土楔形桩及夯实水泥土圆柱形桩复合地基进行了数值模拟,得到了在各级荷载作用下的桩土平均沉降差及桩土应力比,并与无侧向约束条件时进行了对比。结果表明,在侧向约束条件下,与圆柱形桩复合地基相比,楔形桩复合地基能减少桩土沉降差,降低桩土应力比,从而改善复合地基的工作性状,为工程应用提供有益的参考。

| Abstract: | Based on lateral restraint effect of long pile,conducts a numerical simulation with the large FEM software ADINA on the properties of the composite foundation with tapered piles and cylindrical piles under the flexible foundation,obtains the average differential settlements of pile and soil and the pile-soil stress ratio under different magnitudes,and compares it with no lateral restraint.The results show that the working properties of the composite foundation with tapered piles are much better than that wi... |
