摘　　要：简述了GB/T 13476《先张法预应力混凝土管桩》4个不同版本中,压蒸混凝土强度评定龄期的演变过程,分析了PHC管桩常压蒸汽养护和高压蒸汽养护后,其混凝土试件在标准养护条件下不同龄期抗压强度的变化趋势,提出了PHC管桩在压蒸养护时混凝土强度评定龄期1d的合理性建议。The article briefly describes the evolution of the age assessment of the strength of press-steamed concrete in four different versions of GB/T 13476 Pretensioned Spun Concrete Piles,analyzes the trend of the compressive strength of concrete specimens under standard curing after atmospheric steam curing and high-pressure steam curing of PHC piles,and proposes the reasonableness suggestion of the age assessment of concrete strength of 1-day in press-steamed curing of PHC piles.
