Application of FDEM in the study of large deformation mechanisms in deep-buried soft rock tunnels: A case study

Application of FDEM in the study of large deformation mechanisms in deep-buried soft rock tunnels: A case study

The Hutou Beishan Mega Tunnel frequently experiences significant deformation and instability collapse when passing through weak and fractured rock strata, leading to frequent design modifications and adversely impacting the construction progress and costs. This paper employs the finite-discrete elem...
