... ABSTRACT: Rock masses are blocky assemblages formed by networks of natural discontinuities (fractures), such as joints, foliations, shear zones or faults, formed by geological activities. To accurately predict the mechanical behavior of rock mass, it is essential to consider these fractures...

... (GSI) (Marinos, 2005). These parameters along with other data can then be used as inputs for slope stability analysis. The most common approach to cell map areas is to take a cell-– nominally 50'X50' and describe the geotechnical characteristics of the rock, including rock mass and discontinuity...

... ABSTRACT: Clarifying the mechanism of wellbore stability in broken formations is crucial due to the discontinuous deformation and stress characteristics of such rocks. Conventional continuum-based rock mechanics methods need to be improved for these formations. The discrete element method (DEM...

... definition of the safety margins of a room-and-mine pillar layout. The results highlight the advantage of adopting advanced constitutive laws for the rock mass and discontinuities resulting in fully optimized designed solutions in terms of safe and, at the same time, economical designs. 1. INTRODUCTION...

... ABSTRACT: The rock mass strength depends on a combination of non-persistent discontinuities and blocks of rock mass. Currently, the representation of the strength for slope stability analysis includes the joints sets (structural domains) with preferential orientations that generate unfavorable...

... shear tests (DST) are geotechnical tests designed to assess the shear strength and deformation properties of soils and rock discontinuities (MacDonald et. al. 2023). This test can be conducted either in a controlled laboratory setting using core specimens or in the field under in-situ conditions (Sanei...

... ABSTRACT: Bedding planes in sedimentary rocks interfere during HF propagation and create complex networks. This investigation utilized semi-circular bend (SCB) test to analyze how opening mode fractures interact with bedding planes with bonded discontinuities of various spacings...

Typical distributions for these parameters may be approximated by normal, lognormal, or Weibull distributions and discrete distributions for fracture conditions.

... ABSTRACT: Hydraulic plucking of rock blocks bounded by discontinuities is one of the primary modes of scour in unlined spillways. The methods used in the current state-of-practice either model a single block in considerable detail or introduce many simplifications to reduce model runtime...

.... One of the important challenges related to this problem is that, under dynamic train loading, the structural deformation of high-speed railway tunnel strongly interacts with the response of surrounding rock masses. Train loading could trigger discontinuities to slip as well as the deformation...

... ABSTRACT: Rock slope stability is generally controlled by the orientations of the discontinuities present in a rock mass. Depending upon the orientations of these features and the orientation of the slope in question, slope failures may be possible. In this analysis, common analytical methods...

... ABSTRACT: Geotechnical design criteria and geotechnical risk management processes are related to the representativeness and reliability of the geotechnical model. Developments in continuum and discontinuum approaches allowed a better representation of discontinuities, intact rock and failure...

.... INTRODUCTION Rockfall is the continuous movement of a rock down a steep slope instigated by adverse discontinuity orientation, freeze-thaw cycles, inefficient blasting, water presence, weathering, and vegetation on the slope. The rockfall movement is categorized into free-falling, bouncing, rolling...

... surface and the failure mechanism. In contrast, a specific mode of failure is not assumed in DEM, since natural discontinuities, joints, shears, and fractures, as observed in the field can be used to create a more realistic representation of the rock mass such that failure can occur along any...

ABSTRACT: Enhanced geothermal systems (EGS) require assessment of the mechanical instability of rock discontinuities at high temperatures, as fluid injection may change the loading conditions of the surrounding rock. A key challenge in monitoring slip along rock fractures is whether the same...
