摘　　要：通过对15根新疆杨圆柱进行轴压试验,研究了玄武岩纤维(BFRP)布粘贴层数(1层和2层)和粘贴方式(间隔贴和满贴)对圆柱承载力、延性等性能的影响;并与相同试验条件下的方柱进行了对比分析。结果表明:BFRP加固圆柱承载力提高10.7%~26.4%;刚度提高1.0~5.04倍;延性提高29.O%~70.9%。通过对轴压试验下的圆柱和方柱性能比较,可看出:加固后圆柱的承载力、延性优于加固后的方柱。Through the axial pressure test of 15 Xinjiang poplar columns,the effects of the BFRP pasting layer (1 and 2 layers)and the pasting method (spacer and full paste)on the bearing capacity,ductility and stiffness of the cylinder were studied,and the square columns under the same test conditions were compared and analyzed.The results showed that the bearing capacity and deformation performance of BFRP strengthened cylinder were improved, in which the range of bearing capacity of cylinder increased by 10.7%-26.4%,stiffness increased by 1.0-5.04, and the ductility range increased by 29.0%-70.9%.By comparing the performance of cylinder and square column under axial pressure test,it could be seen that the bearing capacity and deformation of the reinforced cylinder were better than that of the reinforced square column.
