隧道衬砌混凝土裂缝原因分析及处理

Study on the causes of cracks on lining concrete of tunnel and treatment measures

结合沙峁沟隧道施工实例,对隧道衬砌混凝土裂缝的原因进行了分析,针对细微裂缝、贯通性裂缝、密集裂缝,提出了具体的裂缝处理措施,对相似条件下施工的隧道出现的裂缝有一定的参考价值。

Combined with practical construction work of Shamao tunnel the reasons caused the cracks on lining concrete of tunnel are analyzed, at the same time according to micro-cracks, through crack and dense cracks practical treatment measures are proposed, which has a certain reference value for similar works of tunnel.
