篮家岩隧道软弱围岩大变形机理分析及综合控制

摘要

随着我国大力发展公路基础设施建设，公路隧道的建设越来越多，且大部分都建于软弱围岩地段。然而在隧道施工过程中软弱围岩的大变形一直是困扰隧道施工的主要问题。对篮家岩隧道软弱围岩中的大变形机理进行系统分析，并提出综合控制措施，以期对今后拟建隧道遇到同类问题的预防和处理有所帮助。%With rapid development of construction of highway infrastructures in China , more and more highway tunnels are constructed and most of them are constructed at weak wall -rock sections .However , large deformation of weak wall rocks during construction of tunnels has been a main problem that puzzles construction of tunnels .This paper systematically analyzes the mechanisms of large deformation in weak wall rocks of Langjiayan Tunnel and proposes comprehensive control measures , hoping to facilitate prevention and treatment for the problems of the same kind encountered in tunnels to be constructed in the future .
