Abstract: Excavating stability of tunneling in permafrost region is related to deep and shallow stability of wall rock. Excavation method is selected by analysis of deep stability. Shallow stability analysis can appraise excavating safe status to guide construction. Real-time controlling system measures convergence and temperature of tunnel, and makes the deep and shallow stability appraisement systems related to tunneling; so construction control and prediction of tunneling come true in permafrost region.

Key words: permafrost, tunnel, excavation, temperature field, control, prediction
