摘　　要：通过粘贴碳纤维增强复合材料CFRP加固新疆杨木矩形截面短柱轴心抗压的试验研究,主要分析了CFRP的粘贴方式(满贴、间隔贴)和层数(1层、2层)对杨木柱的极限承载力、荷载-应变曲线、纵向变形、横向变形等力学性能指标的影响。结果表明:CFRP满贴和间隔贴加固能够显著改善新疆杨木柱的轴心受压性能,并且加固效果满贴方式优于间隔贴方式;随着粘贴层数的增加,两种粘贴方式下加固柱的承载力均呈现增大趋势;当两种粘贴方式层数相同时,木柱的横向变形都得到了有效的约束,约束效果基本一致;而间隔贴加固方式下木柱的纵向变形较大,这种影响随着层数的增加更为显著。By axial compressive experiments on strengthening of rectangular section with CFRP（ carbon fiber reinforced polymer）,it was mainly analyzed the influence of CFRP paste method and layers on the ultimate bearing capacity,load-strain curve vertical deformation and lateral deformation etc of populus bolleana short columns. The result showed that full pasting and intervals pasting of CFRP could significantly improve the performance of axial compression of the populus bolleana short columns,and effect of full pasting was superior to the interval pasting.With the increase of paste layer,the bearing capacity of the column under two kinds of paste methods all showed a trend of increasing; Under two kinds of paste layer,the lateral deformation of the column with the full paste and intervals was effectively constrainted,and their constraint effect was almost the same,the longitudinal deformation of the column with interval reinforcement was larger which was more significant,with the increase of the number of layers.
