... that in the downstream edge fault model, the stress is concentrated at the downstream edge. For both the central fault model and the upstream fault model, the effect of the fault on the stress distribution is small. In the plug installation model tests, the depth of the plug is varied at 10, 30, and 60 mm. From...

Above disadvantages of some realizations of large- scale shear tests cause, that assumptions, which are taken in the interpretation of the results - i.e. homogeneous stress distribution along forced shear plane, shear failure without any tension phenomena - are far...
