Shotcrete tunnel lining

Wet shotcrete, including wet steel fiber shotcrete and wet plain shotcrete, has been adopted for the temporary and permanent lining of Qinling Railway Tunnel and good results have been obtained.

秦岭隧道采用了湿式喷混凝土（包括湿喷钢纤维混凝土和湿喷素混凝土）进行初期支护和永永支护，取得了良好的效果。

The living example show that the technology of deeper fragmenting surrounding rock tunnel repairing by bolting and shotcrete lining is very effective.

通过工程实例证明，锚喷支护技术是一种有效的修复深部破碎围岩巷道的支护技术。
