摘　　要：古牛坡隧道地处贵州省西部高原山区,地形地质复杂,围岩较差。隧道2次衬砌在防火涂料施工完毕后出现开裂。对该隧道2次衬砌裂缝进行监测及处治,使2次衬砌最终达到相对稳定的状态。其2次衬砌开裂处治设计方案对今后类似工程具有一定借鉴意义。Guniupo Tunnel is located in plateau mountain area in the west of Guizhou Province with complicated terrain and geology and bad wall rock. Cracking appeared on the secondary lining after construction of fireproof coating. The secondary lining cracks were monitored and treated,enabling the secondary lining to reach relatively stable status finally. The design scheme of treatment for cracking of the secondary lining exhibits certain reference significance for similar projects in the future.
