摘　　要：地铁车站或盾构井的围护结构一般采用钢筋混凝土材料,在盾构始发与接收前必须破除钢筋混凝土桩,破除过程中存在较大的施工安全风险,工期较长,且会削弱结构强度;在穿越区间既有附属结构时,也存在这些问题。在围护结构中用玻璃纤维筋局部替代钢筋而实现盾构直接切削进行始发,在国内外已经有了较为广泛的应用,在充分总结国内外研究与应用现状的基础上,提出玻璃纤维筋的应用前景,为进一步推广该方法奠定基础。Subway stations or shield wells are often constructed by reinforced concrete supporting structure materials.These concrete retaining structure materials must be destroyed prior to the launching and receiving of shield,which may lead to some security risks during the destruction,and will extend the construction time of the project.As a result,the structure strength may be weakened.These problems also exist in crossing subsidiary structures.In the supporting structure,concrete supporting structure materials have been partially substituted by glass fiber reinforced plastic bars in shield engineering in the world.Application prospect of glass fiber reinforcement was forecast according to the results of research and application in the world,which laid a foundation for further promotion of this application.
