摘　　要：主要介绍了CFRP约束混凝土圆截面短柱轴压状态下的试验过程和试验结果，通过9根圆短柱的静载试验，得知CFRP约束柱在轴心受压情况下，可以大大提高构件的承载能力，其有无预加载的承载能力的提高程度受混凝土强度、结构胶的力学性能、CFRP的强度、粘贴层数、搭接长度等各种因素的影响。In this article, the author mainly presented the experimental process and results of short circular concrete columns reinforced with CFRP under axial compression. Through static tests of 9 short circular columns, the results of the experiment showed that the axially compressed short columns reinforced with CFRP could improve greatly in loading capacity, and the increasing degree of which under primary load or secondary load depends on the concrete strength, mechanical behavior of structural glue, CFRP strength, number of sticking layers, overlapping length, etc.
