Simulation analysis of temperature field of permafrost roadbed
The finite element analysis model of roadbed temperature field in permafrost region is established with finite element software platform. By using this model, the temperature field of roadbed is compared and analysed, and the freezing-thawing depth and variation rule of roadbed are studied. The resu...
