广东白山隧道渗漏水病害分析及处置技术探索

Analysis and Treatment of Water Leakage at Baishan Tunnel in Guangdong Province

营运隧道渗漏水会对隧道衬砌、设备造成损害甚至腐蚀,引起围岩变形并缩短设备使用寿命,严重时造成地面建筑物的不均匀沉降和破坏,从而危害行车安全及隧道运营安全。以韶赣高速白山隧道发生渗漏水等相关病害为例,研究分析了隧道渗漏水产生机理,探讨了隧道渗漏水等常见病害的成因,最终提供了对应的施工组织方案、施工处置技术,供同类隧道病害处置参考。

Tunnel water leakage will cause great damage or even corrosion to tunnel lining and equipment,cause surrounding rock deformation and shorten the service life of tunnel electronic equipment. In some serious cases it can also cause uneven settlement and damage of ground buildings,which will endanger the safety of tunnel’s operation. This paper use the Baishan tunnel in Shaoguan-Jiangxi expressway as an example,analysis the mechanisms of tunnel water leakage,discusses the cause of water leakage and other common diseases in tunnel,and eventually provide a relevant construction organization plans and construction techniques for those diseases,which can used for the treatment of similar tunnel diseases.
