The Qinghai-Tibet Highway and Railway (the Corridor) across the Qinghai-Tibet Plateau traverses 670 km of permafrost and seasonally frozen-ground in the interior of the Plateau, which is sensitive to climatic ...
A proposed classification of 51 zones, sub-zones, and sections of frozen ground has been widely adopted for the design and construction of foundations in the portion of the Corridor studied. ...

The dynamic changes of the thawing and freezing processes of the active layer cause seasonal subsidence and uplift over a large area on the Qinghai–Tibet Plateau due to ongoing climate warming. ...
Our research has important reference significance for the seasonal dynamic monitoring of different types of seasonal deformation and the extensive investigations of permafrost in Qinghai Tibet Plateau. ...
Introduction The total area of permafrost on the Qinghai-Tibet plateau (QTP) is approximately 1.06 ± 0.09 km 2 [1] , which is the largest area of high-altitude discontinuous permafrost in the middle and ...
