Probabilistic assessment of existing shield tunnel longitudinal responses to tunnelling

International journal for numerical and analytical methods in geomechanics (Print)
This paper proposes a probabilistic‐based framework to assess the failure probability of the existing shield tunnel owing to undercrossing tunnelling.

Slurry filtration process and filter cake formation during shield tunnelling: Insight from coupled CFD-DEM simulations of slurry filtration column test

Tunnelling and Underground Space Technology, 2019
The slurry infiltration process plays a crucial role in the slurry shield tunneling process, during which a filter cake is expected to form on the tunnel face to transmit the support pressure.

Analysis of the field monitoring data on soil movements and adjacent building settlement due to shield tunnelling

Engineering computations, 2019
Purpose The shield tunnels closely constructed near the foundations have an inevitable influence on the structures, even results in the large settlement or uplift of the structures.

Design of Shield Tunnel Structures

2019
Shield machine is a steel circular protective device or mobile support. It is suitable for tunnel construction in soft aquifers, especially under the riverbed, seabed, and urban residential areas. The underground structure constructed by the shield method can be simply termed as the shield lining.

Effects of above-crossing tunnelling on the existing shield tunnels

Tunnelling and Underground Space Technology, 2016
Abstract Tunnelling in the dense urban areas frequently results in over-crossing or bypassing the existing tunnels. It is obvious that the over-crossing tunnelling will adversely affect and even damage the existing tunnels if the induced deformation exceeds the capacity of tunnel structures. Increasing concerns have been raised about the interactions
