... and to the so-called grain plane. The rift and grain are weakness orientations, often associated to discontinuity planes typically appearing in granite rock masses. Following this bench face orientation involves working with over-tilted sub-vertical benches (75–85°). This configuration makes easier quarrying...

... to represent the actual slope and the major joints sets were mapped in the numerical model as per their dip/dip-direction observed at the site. The behaviour of the discontinuity sets was modelled using a Mohr-Coulomb slip with residual strength. The normal stiffness of the joints was calculated from rock mass...

... and J2 promotes potential for wedge failure. 1 Introduction The stability of rock slopes is often significantly influenced by the structural geology of the rock in which the slope is excavated. The significance of discontinuities is that they are planes of weakness in the much stronger, intact rock...

... by those clays. Here we analyze the Vajont failure with the numerical DDA method by implementing two alternative friction degradation models: (1) scale dependent roughness degradation, appropriate to clean and initially rough rock discontinuities, and (2) transition from creep to runout, appropriate...

... Abstract Landslides registered in soil massifs in the "Serra do Mar" region are well investigated in the literature, however the presence of geological discontinuities can also trigger planar or wedge sliding associated to rocky massifs. In this context, the main objective of this study...

... Abstract The aim of this paper is to present a practical application of Fuzzy Controllers and Artificial Neural Networks (ANN) models to analyze the stability of rock slopes defined by unfilled discontinuities. Results from direct shear tests on different boundary conditions and types...

... by Leagold Mining Company. The results have demonstrated that the insertion of groundwater into the model is in fact the most important driving factor influencing slope stability. Moreover, the failures observed in 2015 and 2017 seems to be related to specific discontinuities in which the strength parameters...

... and the discontinuity orientations. However, it suffers from the common drawbacks of classification systems. In addition, it is required to be tuned for weak rock mass. This study modifies the classical SMR system by Fuzzy Logic to predict the slope failure mode. Enhancements on the prediction mechanism depend...

The use of the Coulomb method was able to adequately represent the slope stability conditions. Stability analyses highlight the importance of the groundwater table (GWT...
