摘要: 隧道不良地质包括基底富水、松散软弱、大变形、断层或隧底溶蚀破碎带等，为避免隧道无砟道床出现病害，需采用隧底加固措施。基于此，本文主要探讨了树根桩基底加固的施工工艺和质量控制。Abstract: The poor geology of the tunnel includes water-rich basement, loose and weak, large deformation, faults or dissolution broken zone at the bottom of the tunnel, etc, in order to avoid the occurrence of disease on the ballastless bed of the tunnel, reinforcement measures at the bottom of the tunnel are required. Based on this, this paper mainly discusses the construction technology and quality control of root pile foundation reinforcement.
