| 摘 要： | 采用三点试验法,对1根钢筋混凝土对比管道和4根加固钢筋混凝土管道的破坏特征、承载力和延性进行了试验研究。对不同加固材料和不同加固量的钢筋混凝土管道在外压力作用下的承载力、荷载-竖向位移曲线等方面进行了分析。试验结果表明,采用FRP加固钢筋混凝土管道可改变裂缝形态,明显提高其承载力,并对管道的延性有较大程度提高。通过分析CFRP和GFRP加固地下管道的破坏特征、承载力及延性,证明了FRP加固钢筋混凝土管道的有效性,为FRP加固钢筋混凝土管道应用于工程实践提供了有意义的参考。

| Abstract: | In this paper,the failure mode,bearing capacity and ductility behaviors of one contrast reinforced concrete conduit and four strengthening reinforced concrete conduits are studied under three-point loads.The influences of different strengthening materials and amount,the bearing capacity and the fluctuation of load and vertical radial displacement of the conduits under external compression are analyzed.The results indicate that the reinforced concrete conduits strengthened by FRP is an effective measure whic... |
