... (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...

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...

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...

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...
