%X 以FRP加固盾构隧道纵缝接头为试验对象，采用足尺试验方法对加固及未加固的纵缝接头的受力性能及其破坏形态分别进行比较，得到FRP加固接头的破坏机理，并对其加固效果进行总体评价。试验结果表明：在FRP材料黏结良好的情况下，加固接头的转角刚度能够得到提升。<br>A full-scale test was carried out to study the ultimate bearing capacity of the reinforced longitudinal joint and the unreinforced one. The failure mechanism of reinforced joint with composite cavity was obtained and the overall effect of the reinforcement was evaluated. The test results show that on the condition of well bonding, the angle stiffness of joint reinforced with FRP can be improved
