Freezing Aonstruction Technology of Asymmetric Heterologous Tunnel Contact Passage
The risk of deformation is very easy to occur in the tunnel tunnel,so the freezing method is adopted to strengthen the tunnel tunnel.ANSYS software is used to build a three-dimensional model of the asymmetric tunnel contact channel and its formation conditions,simulate the deformation rule and stability of the contact channel under different freezing days,freezing wall thickness,freezing wall condition and freezing temperature,and optimize the construction scheme.The results show that the soil treated by the freezing method has a good freezing effect,the soil strength is high,and the soil is not easy to collapse during excavation.The longer the freezing days,the smaller the displacement change;better reinforcement effect can be obtained under the condition of thicker frozen wall and full frozen wall;the lower the freezing temperature is,the more stable the communication channel is.
