预制钢筋混凝土异形截面桩分析

Prefabricated Reinforced Concrete Pile with Abnormal Section

在截面面积相等的情况下,异形截面桩的侧面周长比方形、圆形及环形截面桩的侧面周长明显要大,从而使桩侧摩阻力显著增大。异形截面桩在某些特定场合下能够最大限度发挥地基土和桩本身的潜在能力,因而可取得有利于承载力提高的力学效果,从而达到节约材料、降低工程造价的目的。

The perimeter of a pile with abnormal sectton is greatcx with circinal section or quadrate section, which makes the friction greater. Under some circumstances the pile with abnormal section can give full play to the potential ability of subgrade soil and pile, thus carrying capacity can be increased obviously, achieving the goal of saving material and reducing project cost.
