Effect of the excavation clearance of an under-crossing shield tunnel on existing shield tunnels

Tunnelling and Underground Space Technology, 2018
Abstract The excavation by earth pressure balance (EPB) shield could cause stress fields varied, which is harmful to adjacent existing structures. Thus the effect of excavation clearance of the EPB shield on the settlement of existing structures should be taken into account.
