The Construction Methods and Control Mechanisms for Subway Station Undercrossing an Existing Tunnel at Zero Distance

The Construction Methods and Control Mechanisms for Subway Station Undercrossing an Existing Tunnel at Zero Distance

The existing tunnel will inevitably be disturbed when the new subway station is constructed cross under it at zero distance. Three innovative construction schemes were proposed, their effects on deformation control were compared by numerical simulations, and the mechanism of the influence of differe...
