<p>The paper argues that, due to challenges such as large uncertainty and presence of ill-posed problems, simple models are well suited to mining geomechanics. It builds its case by defining what models are, outlining the usefulness of simple models, and explaining ...

This paper explores application of the Finite Element Method (FEM) and Shear Strength Reduction (SSR) analysis to compute probabilities of failure for slopes. It does so using two probabilistic approaches: the Point Estimate Method (PEM) and limited numbers ...

<p>In numerical analyses involving multiple geological materials, predicted stress distributions, deformation patterns, and failure mechanisms depend on the ratios of the Young's moduli for the different materials, a detailed often overlooked. Using two simple ...

This paper describes a method that allows direct use of the Generalized Hoek-Brown criterion in Finite Element (FE) Shear Strength Reduction (SSR) analysis of rock slopes. It describes the generation of shear envelopes for the criterion, lowering of the shear ...

This paper examines the application of Finite Element (FE) analysis to the determination of the factor of safety of rock slopes for which strength is modelled by the Generalized Hoek-Brown failure criterion. The paper first outlines the standard shear strength ...

<p>This paper provides an overview of a methodology being used by tunnelling experts, which captures the three-dimensional essentials of tunnel behavior with two-dimensional analysis tools. The methodology allows support designers to start off with reasonable ...

This paper will discuss application of the Shear Strength Reduction (SSR) method, using finite element (FE) analysis, to determine the stability of slopes in blocky/jointed rock masses. It will demonstrate the method's versatility and reliability through analysis ...

This paper examines the question of whether geostatistics really holds much promise for geotechnical engineering, and attempts to identify conditions that if satisfied could convert geostatistics into a real design aid for geotechnical engineers. The paper ...

This paper presents the results of a simulation study of the effect of rock size and shape on impact distance, defined as the distance from the base of a slope to the first point of impact. This study is based on new algorithms which take into account the ...
