| 摘 要： | 分析了轴压及剪跨比对预应力高强度混凝土管桩(PHC管桩)抗剪承载力的影响。结果表明,在剪跨比一定情况下,PHC管桩的极限抗剪能力随轴压的增大有所提高,轴压比与管桩的极限抗剪承载能力近似呈线性关系;增大剪跨比,PHC管桩的抗剪承载力明显降低,其破坏形式也随之发生改变。

| Abstract: | The influence of axial compression and shear span ratio on the shear capacity of PHC piles were analyzed.The results show that the shear capacity of PHC pipe piles increases with the increase of axial compression under the condition of ultimate axial compression,and the relationship between the axial compression ratio and the ultimate shear capacity of pipe piles is approximately linear.Based on the results of simulation analysis and the existing theoretical formulas,the formulas for calculating shear capacity considering the factors of axial compression and shear span ratio are derived. |
