首先介绍了桩基检测的方法并分析了单桩荷载—桩顶沉降、桩端沉降、桩身压缩曲线的特性及其在工程中的应用。
The method of testing the base settlement of pile bottom I's introduced in this paper, How to use the characteristic of P-St, Sb, ss, curve in engineering practice is then discussed.
通过该表达式并依据位移协调法的原理编写的程序，计算出了桩身的荷载沉降曲线。
Then according to the expression and method for harmony of displacement, relation curve between load and settlement was figured out.
通过非线性优化算法，拟合实测的Q—S曲线，可得到桩土系统的工程力学参数，并由此计算得到桩身轴力及侧摩阻力分布曲线。
Measured Q-S curve are back figured by nonlinear optimization approach and model parameters are found simultaneously, then distribution of axial force and skin friction along pile are calculated.
