摘　　要：分析了桩在桩端弯矩和水平力共同作用下桩土共同工作时,用幂级数法求解参数法的微分方程,推导出了桩的内力与位移的具体计算式,从而求得桩身各截面的水平位移、转角、弯矩、剪力,以及桩侧土抗力。The differential equation of parameter method is resolved by Using power-series method. In the paper practical formula is also founded for internal force and displacement calculation of the pile, which is under the interaction of flexural moment and horizontal force at pile tip. Utilizing this method the lateral displacement, turn angle, flexural moment, shear force and the force of soil are acquired.

关 键 词：参数法 幂级数方法 内力 位移
