摘　　要：为完善和改进基于地基系数法的桩身内力计算通解,以文克尔假定和幂级数法为理论基础,推导了考虑桩身计算宽度非线性的通解以及通过简化得到计算宽度线性的通解,并给出相应的通解表达式,从而将目前基于地基系数法的桩身内力计算理论进行发展和统一.通过对其初值条件进行研究总结,得出目前常用的4种桩顶边界和5种桩端边界条件,进而给出其相应的计算表达式,从而解决了横向受荷桩的计算问题.In order to improve the general solution of pile internal force calculation based on foundation coeffi- cient method, the general solution considering the width nonlinearity of piles was derived based on Winkler as- sumption and method of power series, and the linear general solution was proposed through simplification. The present computing theory based on foundation coefficient method was developed and unified as a result of this study. From the analysis of initial value conditions, 4 kinds of pile top boundary and 5 kinds of pile end boundary, which are commonly used at present, were summarized.
