A Finite Element Analysis of Tunnel Lining Demolition by Blasting for Subway Tunnel Expansion

In this paper, a practical project of subway tunnel lining demolition via blasting for the construction of a subway station under the action of the blasting load and the weight of collapsed rock mass was proposed. The tunnel overbreak and underbreak quality, the failure mechanism of the tunnel linin...
