考虑软化效应的桩侧非线性荷载传递模型

On non-linear load transfer models at pile sides with softening effect

在现有荷载传递模型的基础上,提出了单桩简化的非线性荷载传递模型,并介绍了该模型的特点,采用矩阵位移法进行程序编写,计算了某工程现场试桩试验,将计算结果和现场观测数据进行对比,发现能够较好的吻合。

Based on the existing load transfer model,the paper points out the simplified non-linear load transfer model of the single pile,introduces the model,adopts the matrix displacement method to program,calculates the site pile trials,and indicates the better consistency can be found in the comparison of the calculation result and site observatory data.
