Analytical solution of additional response of shield tunnel under asymmetric jack thrust
Rock and Soil Mechanics, 2021 When shield is driving along a curve alignment or during deviation correction, the asymmetrical thrust will generate an additional bending moment at the head of the tunnel, which will cause construction problems such as longitudinal deformation of the ...

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.
