Study on the construction method for in-situ expansion of existing large cross-section tunnels
Abstract This paper takes the in-situ expansion project of the Dachangshan tunnel as a case study to compare and optimize the construction method for the in-situ expansion of existing large cross-section tunnels. The deformation of the tunnel, the stress distribution of the surrounding rock, and the...
