引用本文摘 ? 要：利用ABAQUS 有限元分析軟件建立了PHC600 B-130管樁樁身橫向受剪數值分析模型，分析了不同軸向拉力對空芯管樁和填芯管樁樁身抗剪承載性能的影響。結果表明，隨著軸向拉力的增大，兩類管樁樁身的開裂剪力和極限剪力均明顯降低，相應的極限位移也有降低，樁身延性下降，填芯混凝土對于管樁樁身抗剪承載力的提高效果顯著?；谝幏逗颓叭搜芯砍晒?，結合數值分析數據，提出了考慮軸拉力影響的空芯管樁和填芯管樁的抗剪承載力計算公式。 Abstract: Using ABAQUS finite element analysis software, the numerical analysis model of PHC600 B-130 pipe lateral shear was established, and the influence of different axial tension on the shear bearing performance of hollow pipes and core-filled pipes was analyzed. The results show that with the increase of axial tension, the cracking shear force and ultimate shear force of the two types of pipes are significantly reduced, the corresponding ultimate displacement is also reduced, and the ductility of the pipe is decreased, and the core-filled concrete has a significant effect on improving the shear bearing capacity of pipes. Based on the specifications and previous research results, combined with numerical analysis datas, the shear bearing capacity calculation formulas of hollow pipe and core-filled pipe considering the influence of axial tension are put forward.
