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 …

Tunnels excavated in soft rock under high in situ stress are usually accompanied by large
time-dependent deformation, slow convergence, and long periods of increased support load …

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

The simultaneous impact of excavation-induced stress concentration and mining
disturbances on deep underground mines/tunnels can result in severe and catastrophic …

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

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

Understanding the long-term creep mechanical behavior of granite is critical to evaluating
the safety of the nuclear waste repository. It is unreasonable to extrapolate the creep test …

Bulking characteristics of gangue are of great significance for the stability of goafs in mining
overburden in the caving zones. In this paper, a particle discrete element method with …

Creep deformation of tunnel surrounding rock is a common phenomenon, posing a
significant threat to the safe excavation and stable operation of the tunnel. In response to this …

The mechanical responses of tunnels are time-dependent due to creep deformation of rock
masses, which can result in large deformations on tunnel walls over time and influence …
