Centrifugal Modeling of the Relationship between Tunnel Face Support Pressure and Ground Deformation in Water-Rich Sandy Soil

Applied Sciences, 2022
To investigate the ground deformation induced by the variation of excess/insufficient support pressure in water-rich sandy soil, a series of centrifuge tests in tunnels located at cover over diameter (C/D) ratios equal to 0.5, 1.0 and 1.5 were carried ...

Deformation characteristics of ground with voids induced by shallow metro tunnelling

Yantu gongcheng xuebao, 2019
The existence of the ground voids makes the ground conditions around the tunnel more complex, which may increase the ground surface settlement and even induce collapse during shallow metro tunneling.
