摘要

Through the prediction of climate change on Qinghai-Tibet plateau, the thermal conditions in permafrost region and degenerating range of permafrost are predicted under two different warming conditions with the help of the numerical simulation technique. General design principles of subgrade engineering in permafrost region under climate change are consequently suggested. This paper analyzes and discusses the stability and safety of subgrade engineering in permafrost region under temperature rising and summarizes the effect of climate change on subgrade engineering in permafrost region along Qinghai-Tibet railway.
