摘　　要：通过采用非线性荷载传递函数模拟桩土之间的非线性共同作用 ,提出了单桩轴向刚度的非线性分析方法 ;讨论了桩长、桩直径、桩身材料弹性模量以及不同传递函数类型等因素对桩刚度的影响 ;并把计算值与实测值进行了比较 。A nonlinear analysis method for the axial stiffness of single pile is proposed by using the nonlinear load transfer functions to simulate the interaction between pile and soil.The influences of pile length,pile diameter,elastic modulus of pile material and type of transfer function on the axial stiffness are discussed.The calculated results are compared with the measured values satisfactorily.
