摘要
文章基于荷载传递函数法和固结有限层方法,提出了一种负摩阻单桩的非线性分析法。该法以荷载传递函数法建立了桩土相互作用微分方程,采用了佐藤悟的荷载传递函数模型,用固结有限层理论求解桩周土层随时间和深度变化规律,用矩阵位移法求解微分方程。工程实例的计算结果表明,本文方法的计算结果比较符合实测结果。
Based on the load transfer method and the finite layered method of consolidation, this paper presents a nonlinear analysis method of single piles under negative skin friction. The differential equation for the pile-soil interaction is set up based on the load transfer method. The Kezdis load transfer model is adopted. The ground settlement distribution rule as the depth and time change is derived by the finite layered method of consolidation. The differential equation is solved by the matrix displacement method. The calculation result of an engineering example shows that the theoretical results agree well with the observations.
