| With the development of society and economy and needs of people’s travel, as the large infrastructure construction in the past few five-year plans, the network of national railway and road has been basically formed. Because of the impact of design, construction, materials, complex tunnel surrounding rock’s environment and climate, a large number of tunnels have a lot of diseases such as lining crack damage, lining corrosion, leakage of water, freezing and thawing and so on. The saying that is" Nine seepage tunnels in ten tunnels" just goes to show serious diseases of tunnel seepage. Diseases of seepage in tunnel not only endanger the leakage and short circuit of supply circuit, but also cause the road surface slippery and icy in winter of the north, seriously affecting the safety of tunnel operation, traffic and construction. The study of disease treatment about seepage in tunnel is still in its infancy currently. There are many examples of the failure treatment, thus disease treatment of mountain tunnel seepage remains to be further comprehensive and thorough research.Based on studies of domestic and foreign tunnel waterproofing and drainage, combined with research situation of Shanxi mountain tunnel seepage, the paper has systematically analyzed the cause of mountain tunnel seepage, summed up the features, analyzed formation mechanism and treatment technology. Relying on in disease treatment project in Datong table mountain, design, selection and application of materials, construction techniques of mountain tunnel seepage treatment has been studied. Some methods to prevent from seepage have been made and some useful conclusions have been obtained. |
