| 摘 要： | 在分析水泥搅拌桩复合地基变形机理的基础上,对桩侧摩阻力进行了简化,同时考虑群桩效应,提出了联合应用Mindlin解和Boussineq解求软基内部任一点的附加应力,然后利用这一结果计算沉降的简化计算方法。研究结果可为软土复合地基理论分析和设计提供参考。

| Abstract: | Based on the analysis of deformation mechanism of the cement-soil pile composite foundation,a simplified calculation pattern of the pile side friction is firstly presented.The additional stresses of soft foundation are determined by the suggested solution of Mindlin and Boussinesq.In the meantime,a practical settlement calculation method is provided by considering the pile group effect.The results can provide reference in theory analysis and design for soft composite foundation. |
