TL;DR: In this article, an advanced rotational failure mechanism is developed to compute, in the context of limit analysis, the collapse pressure for tunnel faces in fractured rock masses characterized by the Hoek-Brown nonlinear failure criterion.

TL;DR: In this article, a rotational face collapse mechanism is extended to compute critical pressures, in the context of the upper-bound limit analysis, for tunnels in layered (or stratified) ground.

TL;DR: In this article, a novel application of Bayesian networks (BNs) to predict rock burst is presented, where five parameters (Buried depth of the tunnel (H), Maximum tangential stress of surrounding rock (MTS), Uniaxial tensile strength of rock (UTS), Uníaxial compressive strength of the rock (UCS), Elastic energy index (Wet), and Elastic Energy Index (WET) are adopted to construct the BN with the Tree augmented Naive Bayes classifier structure.

TL;DR: In this paper, a new Mine Slope Instability Index (MSII) to assess the (in)stability conditions of slopes in open-pit mining is presented, using an optimized Back-Propagation Artificial Neural Network that has been trained with an extensive database of worldwide openpit slope stability case histories.

TL;DR: In this paper, Bahaaddini et al. used the Shear Box Genesis (SBG) approach to simulate unbonded planar and triangular joints under CNL and CNS boundary conditions.
