Research on the Application of TBM Method in Mountain Highway Tunnel Construction
With the rapid development of China's economy,the construction of transportation infrastructure is also constantly strengthened.Among them,tunnel engineering is characterized by multi,long,large,high and deep.Tunnel engineering construction is becoming more and more difficult and risky.TBM(Tunnel Boring Machine)method came into being.Compared with the traditional drilling and blasting method,the TBM method has the advantages of high mechanization,good safety and fast construction speed.However,due to the large section of the highway tunnel and the high construction space and cost requirements of the TBM method,it is currently less used in the highway tunnel.This paper expounds the application of TBM method in the construction of mountain expressway tunnel from the aspects of TBM construction parallel guide pit,TBM construction main hole advance guide pit and so on.
