摘　　要：双护盾形式的TBM逐步引入地铁施工,双护盾TBM的适应性较强,可适用于硬岩,也可应用于软岩,但其穿越不良地质时需采取一系列措施,如预加固和控制各项掘进参数等保证安全顺利通过。The TBM in the form of double shields is gradually introduced into subway construction. The double shield TBM has strong adaptability and can be applied to hard rock or soft rock. However, a series of measures should be taken when crossing bad geology to ensure safe and smooth passage, such as to pre-reinforcement and control of various driving parameters.
