摘要：

2-D finite element analysis applied to the roadbed with insulations (Expandable Polystyrene, EPS; Polyurethane, PU) in different depths on Fenghuoshan permafrost zone of Tibet was conducted. By changing the insulation's dimension and position, a series of computer simulations were carried out. The simulated thermal states of roadbed and the base for the modeled cases for the following 50 years are presented and discussed, the main influencing factors were outlined.
