寒区隧道病害成因分析与处治措施研究

The Study on the Cause Analysis and Treatment Measures of Tunnel Defects in Cold Regions

衬砌裂缝及渗漏水是寒区隧道最常见的病害,严重影响隧道的使用寿命和行车安全。结合山西省某隧道病害情况,分析了隧道衬砌裂缝和渗漏水原因,提出了裂缝凿槽注浆补强、W钢带加固和U形槽导流等处治措施,为寒区隧道病害处治提供了一种可行的方法。

Lining crack and water leakage are the most common defects of tunnels in cold regions, which seriously affect service life and driving safety of tunnels. Combined with the defects of a tunnel in Shanxi, this paper analyzed the causes of lining crack and water leakage and put forward treatment measures like crack gouging grouting reinforcement, W-type steel band strengthening and U-shaped slot diversion, which provided a feasible method for treatment of tunnel defects in cold regions.
