摘要
采用三维有限元法进行复合地基承载特性的数值分析研究 ,首先分析一般单桩和复合地基中单桩的荷载传递特性 ,然后研究群桩效应中桩侧摩阻力、桩顶应力及桩身附加应力分布规律与特点 。
This paper made a thorough study on the bearing performances of the composite foundation by means of the finite element method (FEM). First it analyzed the loading transfer of the general single pile and the single pile of the composite foundation. Then the distribution laws and characteristics of the lateral friction force in the group pile effect and the top pre stresses and the additional stresses of pile are studied. The results of this research would provide a theoretical basis for rational design in the composite foundation.
