Effect of discontinuity roughness and anisotropy on shear strength

Denli, Alper Kaan
Discontinuity surfaces generally consist of undulations termed as roughness. It is well known that surface roughness plays an important role on the shear strength and shear behavior of discontinuities. However, the effect of roughness will not be the same when the direction of shearing changes. This effect causes variation of shear strength with shearing direction or in other words anisotropy on shear strength. In this thesis, an experimental study was performed to investigate the effect of roughness and anisotropy on shear strength. For this purpose, joint samples were prepared using a model material and direct shear tests were conducted at different normal stress levels and shearing directions.


Three dimensional numerical modelling of discontinuous rocks by using distinct element method
Koçal, Arman; Karpuz, Celal; Department of Mining Engineering (2008)
Shear strength characterization of discontinuities is an important concept for slope design in discontinuous rocks. This study presents the development of a methodology for implementing Barton-Bandis empirical shear strength failure criterion in three dimensional distinct element code, 3DEC, and verification of this methodology. Normal and shear deformation characteristics of discontinuities and their relations to the discontinuity surface characteristics have been reviewed in detail. First, a C++ dynamic l...
Effects of geometrical factors on fracture toughness using semi-circular bending type specimens
Het, Kıvanç; Tutluoğlu, Levent; Department of Mining Engineering (2008)
Semi-circular specimens (SCB) under three point-bending which are commonly used for fracture testing of rocks were used here for fracture mechanics tests. A total of 65 specimens were tested by using Ankara andesite rock. Investigations including the effects of initial notch thickness, different loading span ratios (S/R), flattened loading end, and little dimensional variations when preparing the specimens were carried out. Stress intensity factors for specimens with different geometries were computed indiv...
Application of Rock Mass Classification Systems for Future Support Design of the Dim Tunnel Near Alanya
Coşar, Songül; Ünal, Erdal; Department of Mining Engineering (2004)
In this thesis, the results of a number of rock mass classification systems applied to Dim-higway tunnel study area are presented. The tunnel ground was classified according to Rock Mas Rating (RMR), Modified Rock mass Rating (M-RMR), Rock mass quality (Q), Geological Strength Index (GSI) and New Austrian Tunneling Method (NATM). Dim Tunnel has a horse-shoe shape, with a diameter of 10 meters and maximum overburden thickness of 70 meters. During studies, the geological and geotechnical characteristics of th...
Effect of cyclic thermal loading on the performance of steel H-piles in integral bridges with stub-abutments
Dicleli, Murat (Elsevier BV, 2004-02-01)
In this paper, analytical equations are developed to estimate the lateral displacement capacity of steel-H piles in integral bridges with stub abutments subjected to cyclic thermal variations. First, steel H piles that are capable of sustaining large plastic deformations are identified based on their local buckling strength. The normalized moment-curvature relationships of these piles are then obtained for various axial load levels. Next, a low-cycle fatigue damage model is employed to determine the maximum...
Effect of boundary conditions on magnetohydrodynamics duct flow
Bozkaya, Canan (2017-12-01)
The magnetohydrodynamic flow of an incompressible, viscous and electrically conducting fluid is investigated numerically in a channel of either rectangular or semi-infinite cross-section with several types of boundary conditions involving walls of variable conductivity in the presence of hydrodynamic slip. The flow is fully developed and driven by a constant pressure gradient in the axial direction under a uniform external inclined magnetic field. The governing differential equations coupled in velocity and...
