<p>The slope stability analysis has many applications in the engineering projects such as the dams, the roads and open pits structures. The method of analysis is usually based on the equilibrium conditions of the potential plane and wedge failures. The zone ...

<p>We examine rockfall susceptibility of folded strata in the Sevier fold-thrust belt exposed in American Fork Canyon in north-central Utah. Large-scale geologic mapping, talus production data, rock-mass-quality measurements, and historical rockfall data indicate ...

<p>This paper applies numerical limit analyses to evaluate the ultimate bearing capacity of a surface footing resting on a rock mass whose strength can be described by the generalised Hoek&ndash;Brown failure criterion [Hoek E, Carranza-Torres C, Corkum B. ...

The analysis of structure using joint set statistics is well known. Other data such as the position of discontinuities and the contacts between rock mass units cannot be easily incorporated in simple statistical analysis based on orientation alone. Algorithms ...

The paper describes the history of the Q-system that was introduced in 1974, and its later development. The individual parameters are analysed, and their relevance for the natural geological features they seek to simulate, is discussed. It is concluded that ...

<p>The intact rock strength of a rock mass has been determined by several different means in the context of research for slope stability assessment. The intact rock strength was determined with unconfined compressive strength testing, Schmidt hammer, Equotip, ...

In this paper, the tests performed on model wedges under static and dynamic loading conditions are described and the existing limiting equilibrium methods are extended to take into account dynamic effects. The applicability and validity of the presented method ...

The RMi (rock mass index) system applies input of block size, joint characteristics and strength of intact rock to express the uniaxial compressive strength of a rock mass. From practical use in more than 5 years the RMi rock support method has been further ...

The RMi system is based on defined inherent parameters of the rock mass and is obtained by combining the compressive strength of intact rock and a jointing parameter. The jointing parameter represents the main jointing features, namely block volume (or density ...

The Rock Mass index, RMi, has been developed to satisfy a need for a strength characterization of rock masses for use in rock engineering and design. The method gives a measure of the reduction of intact rock strength caused by discontinuities given by RMi ...
