Circumferential yielding lining is able to tolerate controlled displacements without failure,
which has been proven to be an effective solution to large deformation problem in …

Tunneling stoppage often occurs during tunnel construction, especially in weak and
rheological ground. The discontinuous excavation caused by the stoppage usually has a …

The conventional constitutive models employed to describe rock mass creep behaviour
associated with the squeezing mechanism are widely adopted in research and design …

When an underwater tunnel is constructed using the drill-and-blast method, the rock mass
around the tunnel undergoes significant blasting damage. Quantifying the combined effect of …

Tunnel excavation in squeezing ground is very challenging due to the difficulty in making
reliable predictions at the preliminary design stage. Tunnel response in squeezing ground is …

Rock mass behaviour model selection, in particular, to represent the post-failure behaviour
and time-dependent behaviour of rock masses, are critical issues in the correct application …

Strainburst occurrence in underground mines is associated with highly stressed brittle and
stiff rockmasses which instantaneously dissipate excess strain energy. This strainburst …

An analytical solution is proposed for the plastic zones developed around two circular
tunnels with unequal size excavated in intact rock which is governed by the Mohr-Coulomb …

In this article, an alternative numerical procedure to calculate displacements and stresses of
supported circular tunnels is proposed, considering the whole process of tunnel …

The time-dependent ground response of tunnels in squeezing ground requires a thorough
understanding of the creep mechanism. Several studies conducted assume that this ground …
