Measured Q-S curve are back figured by nonlinear optimization approach and model parameters are found simultaneously, then distribution of axial force and skinfriction along pile are calculated.
Axial force transmission, distribution of skinfriction, tip resistance of pile, as well as tress ratio between pile and soil are changing with pillow.
研究了褥垫层厚度变化对桩身轴力传递、桩侧摩阻力分布、桩端阻力发挥、桩土荷载分担及桩土应力比的影响。

The axial force of piles first increases with the depth and then decreases. The variation of negative skinfriction with the depth of piles is nonlinear.
