摘　　要：对11根矩形截面新疆杨木梁进行抗弯静力试验,研究在受拉区粘贴碳纤维布加固木梁的抗弯性能,同时对新疆杨木的含水率、顺纹抗拉强度、顺纹抗压强度和局部横纹抗压强度等进行测定。验证平截面假定,并得出破坏特征、极限荷载以及荷载与挠度之间关系等。试验结果表明:在木梁受拉区粘贴碳纤维布是提高新疆杨木梁抗弯性能的有效方法。The flexural static tests were carried out for 11 rectangular Xinjiang poplar beams, and it was studied bending performance in the tension zone bonded carbon fiber cloth reinforced timber beam, at the same time, their basic mechanical properties, such as water content, tensile strength, compressive strength parallel to grain and local transverse compressive strength were measured.It was verified the plane section assumption and got the relations among failure characteristics of load,ultimate load and load-strain.Test results show that bonding carbon fiber cloth in the beam tension is an effective method to improve the flexural performance of Xinjiang poplar beams.
