摘要
在偏心受压钢筋混凝土圆形截面柱强度的基本计算公式基础上,结合支护桩的受力特点,得出了均匀配筋支护桩计算的有关公式,据此制成了计算用表,计算简单且结果准确,适用于不同截面尺寸、保护层厚度以及不同混凝土强度等级和Ⅰ级、Ⅱ级钢筋。
Based on the basic formulas of normal section strength of R. C circular section columns subjected to eccentrical compressive loads, and considering practical mechanical characteristics of supporting piles,authors present the ultimate strength formulas of uniformly reinforced circular section supporting piles. A calculation table according to the formulas is attached. With this table,calculations are simplified and calculation results will be more accurate. This calculation can be used in the piles with different sizes of section, various thicknesses of concrete pretection layer and different concrete strengthes as with well reinforcements grade Ⅰ Ⅱ .
