隧道渗漏水病害的产生原因及整治技术

Causes of Tunnel Leakage and Treating Techniques

渗漏水、结构腐蚀损坏、仰拱问题以及铺底变形是隧道工程常见的病害类型,其中衬砌底部腐蚀损坏造成的渗漏水病害问题更为普遍。通过分析桑植隧道衬砌产生渗漏水的原因、衬砌结构损害形成因素等,针对无水和有水衬砌裂缝、变形缝裂缝采取不同的防治技术,收到良好效果。

Water leakage, structural corrosion damage, invert problems and pavement deformation are the common types of diseases in tunnel engineering,among which the corrosion-caused damage of the lined bottom of the tunnel is even more normal.Upon the basis of the study and analysis of the causes of the lining leakage and the formation factors of the damage of the lined structure of Sangzhi Tunnel, different preventive and control techniques are adopted for treating the cracks of waterless lining, watery lining and deformation joints, with very good results obtained.
