Simulation and Analysis of Frost Heave Force for Tunnel Lining
With the high-latitude and high-altitude tunnel built, researches on frost damage mechanism of the tunnel and prevention countermeasures have become imperative. By numerical simulation of tunnel lining-scaled model at different temperature boundary conditions, changes of the stress state with no insulation material and insulation materials of poly phenolic under water-saturated and natural conditions were discussed. Through the analysis, it’s indicated that the tunnel waterproofing and insulation are equally important in the alpine region. The results has important reference and guidance significance in design and construction of the tunnel under cold weather conditions.
