Significance of Numerical Simulation Research on the Thermal Regime of the Subgrade in Permafrost Regions

Ling Feng  
The study of the thermal regime of the roadbed in permafrost regions,and the prediction of its dynamic characteristics are the precondition to improve the technologies of constructing highway and to harness the freeze damages in permafrost regions, and also the basic works to keep the road surface even,the roadbed stable, and to ensure the physical landscape along the highway improved step by step. Thispaper discusses the significance of the study on the thermal regime of the roadbed in permafrost regions,and the feasibility, necessity and prospect of the study on the thermal regime of the roadbed in permafrost regions by using the numerical simulation.
