摘要
本文对推力桩地基反力系数提出统一的模型，并推导出相应的通解．过去，在小荷载阶段地基反力系数采用其它模型而无解析解，只能用数值法求解，从而大大增加参数反算的难度．通过理论证明、实例的理论解与实测结果和数值分析结果的对比分析，说明该通解是正确的，适用于分析推力桩各个荷载阶段．
An united model for determining the nonlinear subgrade reaction coefficient is proposed and its general solution is derived in this paper. In the past, it was difficult to determine the coefficients since some other model was adopted in the low loaded stage. Its theoretical solution can not be derived and its result can be got only by the numerical methods. It is proved in this paper that the general solution is right and suitable for analysing alterally loaded pile in the whole loading process by comparing theoretical analysis results with the experiment and numerical analysis results of living examples.
