摘　　要：预应力高强混凝土(PHC)管桩是桩基工程中应用的主要桩型之一,文章从宏观力学性能、耐久性和微观结构等方面对PHC管桩混凝土国内外研究进展进行了总结。目前关于PHC管桩混凝土的研究大都是围绕振动成型试样展开,未能考虑PHC管桩离心成型过程对混凝土性能的影响,建议采用与PHC管桩同材料、同养护条件、同等离心过程制备的混凝土试样,开展宏观至微观的多尺度系统研究。Prestressed high-strength concrete(PHC)pipe piles are one of the main pile types used in pile foundation engineering.This article summarizes the research progress of PHC pipe pile concrete from the aspects of macro-mechanical properties,durability,and microstructure,both domestically and internationally.Currently,most research on PHC pipe pile concrete is carried out using vibration-formed specimens,without considering the impact of the centrifugal forming process of PHC pipe piles on concrete properties.It is recommended to conduct multi-scale system studies from macroscopic to microscopic levels using concrete specimens prepared with the same material,curing conditions,and centrifugal process as PHC pipe piles.
