摘　　要：三参数算法以幂级数的形式给出了推力桩基本微分方程的理论通解,可以实现对桩顶挠度、转角、弯矩、剪力和桩身极大弯矩及其所在位置的拟合.文中通过理论推导与分析,给出了三参数算法反演求解所需的所有基本方程,介绍了反演求解的基本过程,明确了幂指数n的实用取值范围,实现了三参数算法拟合所需参数的求解,为三参数算法的实际应用奠定了基础.并且给出了一个试桩拟合实例.The 3-parameter theory gives the common solution of laterally-loaded pile′s differential equation in the form of power series.The results calculated by 3-parameter theory can accurately match the deflection,rotation,moment,shear tested on the top,and the maximum of moment.By theoretically deducing and analyzing,all necessary formulas for the inversion of 3-parameter theory of laterally-loaded pile are given in this paper.The method of this inversion is introduced.Moreover,the practical range of n,a key parameter is defined.The fundamental theoretical system of 3-parameter theory is completed.At last,a test pile′s performance is matched with the 3-parameter theory.
