Fault fracture zone is a common engineering geological condition in mountain tunnel
excavation, which often brings great difficulties to engineering construction. Thus, uniaxial …

A rock mass containing non-persistent joints can only fail if the joints propagate and
coalesce through an intact rock bridge. Shear strength of rock mass containing non …

The existence of defects in a rock mass is a vital factor complicating the mechanical
response of the rock mass under stress. The characteristics of defects control the rock …

Step-path failure is a typical instable mode of rock slopes with intermittent joints. To gain
deeper insight into the step-path failure mechanism, six rock slopes with different intermittent …

The uniaxial compressive failure mechanism of rock like specimens with arched shaped
notches was studied experimentally and numerically considering the effects of cracks' …

Predicting rock cracking is important for assessing the stability of underground engineering.
The effects of the intersecting angle α and the distribution orientation angle β of intersecting …

Grouting reinforcement is a common way to strengthen fractured rock mass in rock
engineering, which will transform the natural open flaws in rock mass into filled flaws. The …

The traditional fracture criterion performs well when calculating crack propagation under
tensile conditions, but a zigzag crack propagation path was obtained under compression …

This study focuses on the effect of pre-existing flaw geometry on mechanical behavior and
crack coalescence modes of sandstone specimens containing combined flaws with different …

The wing crack initiation and propagation of the inclined crack under uniaxial compression
is the key factor affecting and controlling the cracked rock mass mechanical behavior …
