| 摘 要： | Aiming at the stabilization of Qinghai-Tibetan Railway embankment during its construction and run, the method using tilt pipes to keep the permafrost embankment stabilization is put forward in the paper. By gathering natural cold energy in the winter and release it in the summer the tilt pipes can keep the permafrost embankment stabilizing. The temperature fields of the embankment and the stratums below are studied according to the condition of pipes diameter 250mm, length 7. 0m and tilt angle 30°,45°, 60° until the railway working for 20 years. It is shown that the embankment field using tilt pipes will eliminate the thawing core and come into subzero temperature phase ahead of 9 years compared with the original model. Different tilt angles have different efforts on the embankment and stratums, synthesis analysis of thermal income and expenses of the embankment and stratums should be carried out
