Abstract EN
An experimental study of a rock-like material containing a preexisting fissure subjected to loading and unloading triaxial compression is carried out, and the results show that the mechanical characteristics of the rock-like specimen depend heavily on the loading paths and the inclination of the fissure.
The triaxial loading experiment results show that the failure strength linearly increases, while the residual strength linearly decreases with increasing inclination.
Furthermore, specimens subjected to triaxial compression show an “X”-type shear failure mode.
The triaxial unloading compression experimental results show that specimens with different inclination angles have various failure modes.
Specimens with gentle inclinations show a tensile-shear mix failure mode, specimens with middle inclinations show a shear-sliding failure mode, and specimens with steep inclinations show a tensile failure mode.
These findings can be used to forecast excavation-induced instabilities in deep underground engineering rock structures.
