剪切位移传递法确定单桩承载力

剪切位移传递法的主要特点是将桩侧摩阻力与端阻力分开考虑 ,通过位移协调将二者再联系起来。计算时将桩分成若干微小单元 ,根据桩的沉降由桩尖位移和桩身压缩量两部分之和组成 ,列出n元非线性平衡方程 ,解此n元非线性方程组并用迭代法可求得在一假设桩尖位移下桩顶竖向作用力 ,从而预估出单桩在竖向荷载作用下的荷载 沉降曲线

DETERMINATION OF THE BEARING VALUE OF A SINGLE PILE BY SHEAR DISPLACEMENT TRANSFER METHOD

Shear displacement transfer characterised via separate analysis of side friction and tip resistance,and then associating them through displacement coordination.In calculation a pile is divided into several microunits and a lot of nonlinear equilibrium equations are written out based on the subsidence of a pile including point displacement and anount of pile compression. The solution of the equation sets and the use of iteration method lead to the vertical bearing value by assuming that there is a point displacement and a load\|settlement curve line of a single pile under the effect of vertical load,can also be estimately figured out.
