Full text not available from this repository.Abstract
The paper presents summary of the work carried out by the author on the modeling of jointed rock mass with some field applications. The practical equivalent continuum analyses approach presented attempts to use statistical relations, which are simple and obtained after analyzing a large data from the literature on laboratory test results of jointed rock masses. Systematic investigations were done including laboratory experiments to develop the methodologies to determine the equivalent material properties of rock mass and their stress-strain behavior, using a hyperbolic approach. Present study covers the development of equivalent continuum model for rock mass, implementation of the model in FLAC3D for 3-dimensional applications and subsequently verification leading to real field application involving jointed rocks. The model was rigorously validated by simulating jointed rock specimens. Element tests were conducted for both uniaxial and triaxial cases and then compared with the respective experimental results. The numerical test program includes laboratory tested cylindrical rock specimens of different rock types, from plaster of Paris representing soft rock to granite representing very hard rock. The results of the equivalent continuum modeling were also compared with explicit modeling results where joints were incorporated in the model as interfaces. Several case studies have been presented with the developed model.
