摘要
本文先提出消除负沉降公式,使分层总和法应用于单桩分析中。接着,提出用桩土间刚塑性滑动的模型和用试验P—S曲线中点吻合反算地基模量系数β,来解单桩的非线性分析。本文主要是解任意层状地基中单桩的分析,具有方法简单,精确性好和仅需常规地基参数等优点,为研究桩基础与上部结构共同作用给出可行的单桩计算方法。
A formula to eliminate negative settlement is presented in this paper, so that the layering summation method is enable to apply to the elastic analysis of single pile. Afterwards, the rigid-plastic model of pile-soil slip and method of backfiguring out the soil modulus coeficient β by the coincidence of the mid-point on the test curve of P-S are proposed to solve nonlinear analysis of single pile. The main result of the paper is to solve the analysis of single pile in arbitrary layelring soils that has advantages of simple and accurate approach and the needful routitie soil parameters, and provids the feasible formula of single pile for researches on interaction between pile foundation and superstrtic ture.
