Η εξέταση της συνοχής καθώς και της γωνίας τριβής των πετρωμάτων πριν και μετά την πολυεπίπεδη τιραξονική θραύση. (EL)
During this diploma thesis, which was carried out in the Tunnelling Laboratory of the School of Mining and Metallurgical Engineering of the National Technical University of Athens, 17 multi-stage triaxial compression tests were performed in various types of rocks. The series of experimental tests include multiple failure tests on rock specimens while recording the axial displacements with Linear Variable Deformation Transducers (LVDTs). The results of the tests resulted in conclusions about the mechanical parameters of the rocks, the internal friction angle and the cohesion. Performing several stages - consecutive loading cycles with an increase in lateral pressure, the transition from the brittle to ductile state and the influence of lateral pressure on the change in the mechanical behavior of the rock were observed. This diploma thesis will deal with the annotation of the failure of the specimens as well as the shape of the curve to the remaining strength. An assessment will also be made of the success of the tests based on the charts resulting from the measurements, as well as a summary and evaluation of the peak strength parameters, the residual strength parameters and the shape of the residual strength envelope.
