桩侧阻力先于桩端阻力的发挥，桩的沉降量主要是桩身压缩量。
The side friction is mobilized earlier than the tip resistance and the pile settlement is mainly the compression of pile shaft compression.
验证了桩侧阻力与接触面两侧切向位移差之间关系可以用双曲线表示。
It was validated that the relationship between the side resistance of piles and the difference of tangential displacement between two sides of the pile-soil interface could be expressed by hyperbola.
表明孔壁粗糙度越大，相应的桩侧阻力就越大，从而提高钻孔灌注桩的承载力。
The result shows that bigger hole coarsenesses have bigger side pile resistance so as to improve the bearing capacity of bored - pile.
