摘要
对隧道围岩大变形发生机制进行了研究,并对隧道围岩大变形进行了重新定义,在对二次衬砌作用机理进行分析的基础上,重点对衬砌裂缝的稳定性展开了分析研究,并得到一系列研究结论,能够为衬砌病害的研究提供一定的理论支撑。
This paper first studied the mechanism of big deformation of surrounding rock in the tunnel,and to redefine the large deformation of tunnel surrounding rock. Based on the analysis of the secondary lining mechanism,we had emphasizes on the stability of lining crack,and get a series of research conclusion that can provide certain theoretical support for the research on lining disease.
