摘　　要：采用灌胶加固的方式对6根带有干缩性裂缝的新疆杨木矩形截面短柱进行轴心受压试验,研究结构胶对木柱极限承载力、横向和纵向应变、纵向变形和横向变形等性能指标的影响。试验结果表明,相对于未加固柱,采用结构胶加固木柱,其极限承载力提高了15%左右,纵向变形和横向变形都得到了一定的改善,表明采用灌胶加固的方式对加固要求不高的构件在一定的范围内是可行的。Axial compressive tests were carried out for 6 rectangular cross section populus bolleana timber short columns with dry shrinkage cracks strengthened with glue reinforcement to study the effects of the structural adhesive on load-bearing capacity,lateral longitudinal strains longitudinal deformation,lateral deformations. The results showed that the ultimate bearing capacity was increased by about 15%,the longitudinal deformation and the lateral deformation were improved to a certain extent. Thus,within a certain range strengthening some members whose requirement for bearing capacity is not high was feasible.
