Permafrost Engineering Problem along the Qinghai-Tibet Railway:A Thorough Research and Practice

Since the beginning of the Qinghai-Tibet Railway construction, the research of the permafrost engineering, synthesizing the previous achievements in permafrost studies, has obtained good fulfillment results. Viewing with system engineering theory, the research aims at the influence of large-scale construction practice on permafrost and permafrost environment and the interaction of permafrost and permafrost engineering, and takes the engineering deformation as the comprehensive goal, and the thermal mechanisms of permafrost engineering problems as the essence. The engineering thermodynamic structure is taken as the main measures to solve problems. At the same time, the study of permafrost engineering and the construction in permafrost regions are promoted to a new level, and a solid technical foundation is established for constructing a top-grade plateau railroad in world.
