用玻璃纤维筋代替盾构围护结构中的钢筋，不但保证了盾构井围护结构的安全，而且使盾构始发、到达施工时不需要人工破除洞门，减少了盾构施工的安全风险。介绍玻璃纤维筋的性质，论述在盾构始发和到达井围护结构中的应用方法及应用效果，并对今后的设计、施工提出了建议。

The use of GFRP to replace the rebars in the retaining structures of shield launching/arriving shafts can not only ensure the safety of the retaining structures, but also can minimize the safety risks in shield boring due to the canceling of the manual dismantling of the retaining structures during shield machine launching and arriving. The characteristics, application method and application effect of GFRP in the retaining structures of the shield launching/arriving shafts are introduced in this paper, which can provide reference for the design and construction of similar works in the future.
