... to model fault-slip occurring along the core. The analysis result shows that the model yields a fault-slip with the maximum shear displacement as much as 0.14 m ( M w = 2.55), whilst the maximum shear displacement produced in a homogeneous, isotropic model is merely 0.038 m ( M w = 2.03), implying...

... proportional equivalent injected flow rate into the fault as the input. This model was validated by comparing the resultant pressure and normal and shear displacements calculated at the centre of the fault against observations from a decametre-scale in-situ experiment. The main results were that not only...

... anchorage modes (i.e., full-length bond and full-length non-bond), different vertical normal stresses, and different prestress were designed. The results show a significant difference in the shear displacement curves between the full-length bonded anchor cable and the full-length unbonded anchor cable...
