摘　　要：研究和分析了螺旋箍筋对预应力高性能混凝土 (HPC)管桩力学性能的影响 ,由试验及理论计算 ,可知螺旋箍筋能使管桩混凝土的强度、塑性、延性及抗震性能有明显改善 ;并提出了螺旋箍筋对提高管桩混凝土强度及承载力的计算公式 。The effects of spiral bars on the mechanical properties of prestressed high performance concrete (HPC) tube pile are analyzed. It is verified through experiments and theoretical calculations that the spiral bars significantly increase the member's strength, plasticity, ductility and anti-seismic capability. And calculation formula are inferred, which make it convenient for tube piles design and research.
