The use of yielding supports has proven to be a highly effective measure for tunneling in
squeezing grounds because of their agreement with the law of mechanical movement of …

The characteristics of rock instability precursors and the principal stress direction are very
crucial for the prevention of geological disasters. This study investigated the qualitative …

Brittle failure, also known as rockburst, is a violent phenomenon that occurs during the
excavation of hard rock in areas with high geostress, particularly at great depths. The …

The safety of circumferential yielding lining is influenced significantly by the shotcrete
hardening property. However, presently, negligible research attention has been paid to this …

During the construction of underground engineering projects, it is often confronted with
complex conditions such as high stress, extremely soft rock, and strong disturbance …

Predicting duration and cost of tunnelling projects is an essential factor in determining the
usefulness of a decision-making system. Therefore, research on the duration and cost of …

Isolated pillars in underground mines are subjected to uniaxial stress, and the load bearing
cross-section of pillars is commonly rectangularly shaped. In addition, the uniaxial …

Early identification of abnormal regions is crucial in preventing the occurrence of
underground geotechnical disasters. To meet the high-accuracy detection requirements of …

The large deformation disaster is a major engineering problem that has not been sufficiently
addressed in tunnelling in soft rock mass. Previous investigations essentially focused on …

Highlights The radius of the plastic zone and the radial stress is introduces into the stress-
intensity ratio. A new rockburst criterion is proposed to predict the rockburst classification …
