摘要: 新奥法的主要承载结构是初期支护,初期支护变形基本稳定后才进行二次衬砌,因此是二次衬砌的基础.通过 对隧道初期支护沉降原因的分析,提出了针对该段不均匀沉降的整治措施.

关键词: 隧道, 初期支护, 沉降, 加固

Abstract: The main load-bearing structure in NATM(New Austrian Tunneling Method)is initial support.The second lining establishes after the deformation of surrounding rocks and initial support the basis of the second lining—-has been basically stabilized.The Causes of the initial support subsidence in Zhongxing Tunnel are an alyzed.A method for renovating the subsidence is presented.

Key words: tunel, initial support, sub sidence, reinforcement
