摘　　要：多年冻土隧道工程开挖施工的稳定性受深层和浅层稳定的影响。通过深层稳定分析选择开挖方案及对浅层稳定分析,评价开挖施工的安全状态,以指导施工作;通过实时监控隧道收敛值和施工温度场的变化,将深、浅层稳定评估子系统与实际工程联系起来,以实现多年冻土隧道工程的施工控制与预报。Excavating stability of tunneling in oermafrost region is related to deep and shallow stability of wall rock. Excavation method is selected bv analvsis of deeo 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.
