摘要
针对公路隧道的裂缝问题,结合青莱高速公路马莱段城岭隧道初砌裂缝的监测工作,分析了隧道典型裂缝的基本特征及产生原因,得出偏压、纵向沉降差、施工工序等是隧道裂缝产生的主要原因的结论。
Crack is the common disease of the tunnel construction. In this paper,the reasons and characters of some typical lining crack is analysed. Which is revealed based on the field monitoring of the lining cracks. The bias rock pressure, the different longitudinal settlement of the lining and the irrational construction proce are the main reasons causing the lining cracks.
