摘要
针对桩在桩端弯矩和水平力共同作用下桩土共同工作时，用ｍ法求解无法得出解析解，而用有限元法和差分法给出的解不尽人意的具体问题，用幂级数法求解了ｍ法的微分方程，推出了桩的内力及变形的具体计算式，并编制了计算程序．
When the pile is subjected to the joint action of horizontal load and bending moment at the pile end and the reaction of foundation soil, the analytic solution by means of m method can not be obtained and the solutions obtained by means of finite element method or finite difference method are not satisfactory. Aimed at this specific problem, a power series solution to the differential equation with the m method is obtained, the formulas for evaluation of pile internal force and deformation are derived, and the evaluation program is developed.
