During the construction of an underground excavation, damage occurs in the surrounding
rock mass due in large part to stress changes. While the predicted damage extent impacts …

Drill-blast method is one of the important methods in the current subsea tunnel excavation
construction. Controlling the vibration effect during blasting construction and its impact on …

The time-dependent (creep) behaviour of rocks affects the safety and stability of tunnels
excavated in weak rocks and at great depths. Several theories have been proposed to …

As rock bursts are unavoidable in deep mines and excavations with high in-situ stresses,
ground support systems are implemented to manage and mitigate rock bursts. Cable bolts …

Deep underground excavations within hard rocks can result in damage to the surrounding
rock mass mostly due to redistribution of stresses. Especially within rock masses with non …

Tunnelling related hazards are very common in the Himalayan terrain and a number of such
instances have been reported. Several twin tunnels are being planned for transportation …

In recent years, with the development of urban rail transit, more and more attention has been
paid to the vibration problems caused by its operation. As the main form of urban rail transit's …

In deep and high stress hard rock mines, large deformations are often associated with the
presence of foliation. Traditionally, the study of the non-linear anisotropic response of …

The convergence-confinement method (CCM) is a method that has been introduced in
tunnel construction that considers the ground response to the advancing tunnel face and the …

The failure process of brittle rocks under compression involves the initiation, accumulation
and propagation of tensile fractures before peak stress is reached. This process is …
