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 ,为复合地基的定量设计提供理论依据
The three-dimensional finite element method is used to analyze the bearing behavior of composite foundations. Firstly, the load transfer characteristics of single pile in common single pile and composite foundation are analyzed. Then, the lateral friction, pile top stress and pile additional stress Distribution rules and characteristics of the composite foundation to provide a theoretical basis for the quantitative design
