Abstract_Chinese:为研究轴压力作用下预应力高强混凝土(PHC)管桩的抗震性能, 本文采用非线性有限元软件ABAQUS对PHC管桩进行了非线性有限元分析, 有限元分析结果和试验结果吻合较好, 表明该有限元模型参数可靠．在此基础上, 利用该有限元模型参数对PHC管桩进行了变参数分析, 分析了轴压比、非预应力筋、剪跨比和箍筋间距对PHC管桩的影响．研究结果表明：轴压比、非预应力筋和剪跨比是影响PHC管桩受力性能的主要因素, 然而改变箍筋间距对PHC管桩的受力性能影响较小．
Abstract_English:To study the seismic behavior of prestressed high strenghth concrete(PHC) pipe piles under axial load，the nonlinear finite element analysis by the software ABAQUS was conducted and the calculation results agree well with test results，which validates the reliability of the parameters of finite element model. Then the parametric analysis using the parameters of finite element model was carried out to further study the mechanical behavior of prestressed high strength concrete pipe piles. The axial compression ratio，non-prestressed reinforcement and shear span ratio are the main factors which have impact on the mechanical behavior of prestressed high strength concrete pipe piles，whereas the stirrup spacing has relatively small influence on the mechanical behavior.
