Climate warming could aggravate the frequency of thaw settlement hazards along the Qinghai-Tibet Engineering Corridor (QTEC), and bring negative impacts on the infrastructures. In this paper, the volumetric ice content and the change of active-layer thickness are taken as indexes and applied to the thaw settlement model supported by ArcGIS software to zone the thaw-settlement hazards along QTEC. The results show that in the next 50 years the thaw settlement hazards along QTEC will be moderate and high-risk categories under A1B and A2 scenarios, but low and moderate risk categories under B1 scenario. High-risk areas mainly distribute in warm and ice-rich permafrost regions, such as Chumarhe high plain, Wudaoliang and Kaixinling regions.
