英文摘要After six years construction, the Qinghai-Tibet Railroad (QTR) was completed in 2006 and it has been successfully operational for two years. QTR crosses about 632 km of permafrost regions. A large fraction of the permafrost region is warm, ice-rich permafrost, which makes it much more difficult to construct any infrastructure system on it. Permafrost scientists and engineers have utilized the state-of the-art technology to actively cool the permafrost under the railroad embankment and to ensure stability of railroad embankment. For the first time, a crushed rock layer was used to cool the permafrost under the embankment in such a huge project. This paper provides an overview of these measures used to cool the permafrost and discusses potential long-term problems. Although the Qinghai-Tibet Railroad is referred as a "green" project, potential long-term environmental impacts should not be underestimated. (C) 2008 Elsevier B.V All rights reserved.
