Unit tests on shield tail brush annular sealing system and its watertightness mechanism
The shield tunnelling method has become the mainstream construction one for urban subway tunnels. Due to the poor sealing effects of shield tail brushes, many severe safety accidents such as water and slurry leakage occur frequently.

Effects of Jack Thrust on the Damage of Segment Lining Structure during Shield Machine Tunnelling
Constructing a tunnel with a large longitudinal slope and a small-radius sharp curve is challenging. During the construction process, it necessitates a series of intricate operations, including adjusting the horizontal and vertical posture of the shield ...

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

Three-dimensional numerical simulation of slurry fracturing during shield tunnelling
The slurry shield tunnelling is an important construction method which is widely applied in tunnel engineering. This method can lead to slurry fracturing failure to the stratum under complex conditions. However, there is no readily available method which
