摘要
从桩—土相互作用的机理出发 ,建立了置于非均质地基中负摩擦桩荷载传递的弹性微分方程 ,利用太沙基一维固结理论和土层分层总和法求得堆载作用下土层沉降随深度和时间变化的规律。由此求得置于均质地基土中桩基弹性微分方程的解析解 ,用有限差分法研究了非均质地基土中的情况 ,同时考虑了地基土的非线性特性 ,并对某一工程实例进行分析论证。
Based on pile-soil interaction,this paper sets up the elastic differential equation for the negative pile in the inhomogeneous ground.The ground settlement distributed rule as depth and time is derived from terzaghi one dimensional consolidation theory and layer-wise summation method.The analytic solution on the elastic differential equation for the pile in the homogeneous ground is derived from this.The case of the inhomogeneous ground is studied by the finite differential method,and soil nonlinear characteristic is considered.At last,an engineering example is studied by this method.
