The affection of artificial freezing method construction to the surrouding environment to the subway tunnel in the soft soil area

QIN Aifang,ZHANG Ya,SHI Yuer(Shanghai University,Shanghai 200072,China)  
With the help of COMSOL the large computer software,we have simulated the stress distribution of the soil around,the influence that comes from the permafrost's freezing to the tunnel and frozen soil's stress and deformation after excavating the permafrost which sets the side channels from Gudai Road Station to Donglan Road Station of the No.12 urban rail transportation line as calculation model.Through analysis the frozen wall freezing during the construction of channel besides the subway and the analysis the stress and deformation for the tunnel and soils when the frozen wall have been excavated.We can get the influence law and properties which the construction to the surrounding environment during the two stages to provide the reference for tunnel excavation in deep permafrost.
