摘　　要：应用ANSYS10.0有限元程序建立了生态复合墙体有限元分析模型;建立弹簧单元模拟群桩基础,采用Davies方法确定桩的刚度;对生态复合墙结构在土-桩-结构相互作用下在竖向荷载下的轴力分配问题进行了数值计算分析。通过对大量的有限元分析数据应用分离变量的二维曲线拟合方法,建立了竖向荷载作用下生态复合墙体各构件轴力分配系数的实用设计计算公式。This paper used ANSYS10.0 finite element program to establish eco-composite wall finite element analysis modeh The substructure technique was adopted to simulate pile group with a group of springs,the grouped pile stiffness was determined with Davies method. The axial force distribution of ecological composite wall structure under the soil-pile-structure interaction un- der the vertical load is analyzed in numerical calculation. By means of finite element analysis of a large number of data based on two-dimensional curve fitting method of separation of variables, set up the practical design calculation formula of axial force distri- bution coefficient of ecological composite wall components under vertical load.
