Abstract

Based on the heat-moisture-deformation coupling model for freezing soil proposed by the authors which took into account three phase medium of soil skeleton and ice and water and its analysis software 3G2001, a coupling numerical simulation analysis for the Huashixia roadbed was conducted and in-site measurements results for Huashixia roadbed were also introduced to compare to the numerical results of the proposed model. The deformation of frozen soil roadbed was divided into four phases, which included the intense frozen heaving, the continual frozen heaving, the intense thawing and the continual thawing from the road surface deformation. The results indicate that numerical results of the temperature field variations along the roadbed depth at different time are with very good correlation to the measurements, and so do numerical results of the relatively freezing deformations of road surface, both numerical accuracy to the measurements are within 10%~20%. The comparison analysis shows the proposed theoretical frame and its numerical modeling for the temperature-moisture deformation coupling behaviors are suitable and acceptable.
