| Abstract: | Based on the simplified air-heat pipe-soil heat transfer model,heat pipe subgrade 3D heat transfer model is established by ANSYS FEM system.With the background of climate and geological geology conditions in Beiluhe Region of Qinghai-Tibet Railway,simulation and comparison of normal subgrade and heat pipe subgrade were completed,and temperature field variations of normal subgrade and heat pipe subgrade at various time were collected. |
| Keywords: | Numerical simulation Heat pipe Permafrost subgrade Heat transfer Temperature field |
