摘要
二次衬砌顶部脱空已成为比较严重的隧道质量通病。通过对公路隧道二次衬砌顶部脱空产生原因进行分析,从力学角度探讨二次衬砌顶部脱空的危害,并提出具体的处理措施。
The separation on the top of secondary liner is one of the common failures of tunnel. This paper concludes the reasons for the separation on the top of secondary liner, analyzes the hazard of it and puts forward specific process measures.
