Having shorter diameter and lower lateral bearing capacity, driven piles are usually used to carry vertical load and can be calculated as axial compressed member.
打入桩，桩径较小，水平承载能力很低，人们一般只用它承担垂直荷载，这样可近似按轴向受压构件计算。

Stationary binomial process is applied to establish practical load model and resistance model for axial compressed member.
