【摘要】 利用有限元软件ABAQUS对管桩建立数值分析计算模型,与在室内条件下的PHC-400-B-95-1400管桩抗剪承载力试验进行了对比,验证了建模的合理性。在此基础上,模拟分析了混合配筋对PHC管桩抗剪承载力的影响,得出不同直径和不同级别条件的混合配筋PHC管桩的破坏形式基本一致,各种形式下的混合配筋PHC管桩其抗剪承载力有所降低,但对其抗剪承载力影响程度并不明显。更多还原

【Abstract】 Using the finite element software ABAQUS to establish the numerical analysis and calculation model of the pipe pile, the model was compared with the shear bearing capacity test of the PHC-400-B-95-1400 pipe pile under the indoor conditions, and the modeling was reasonable. On this basis, the effect of hybrid reinforcement on the shear capacity of PHC pipe pile was simulated and analyzed. It was concluded that the failure modes of PHC pipe pile with different diameters and different grades of hybrid reinforcement are basically the same, the shear bearing capacity of the hybrid PHC piles in various forms has been reduced, but the influence on the shear capacity was not obvious.更多还原
