To investigate the permeability changes and the mechanisms of fractured rock under dynamic and static stresses produced by earthquakes, permeability experiments on fractured rock with rough surfaces under axial dynamic and static stresses were conducted on the MTS815 Rock Mechanics Testing System.

Surface asperity was investigated by scanning the specimen surfaces before and after testing.

The results show that the roughness of fracture surface has a great influence on the permeability when the axial displacement is not enough to cause the fracture rock to slip.

Moreover, the rougher fracture surface leads to severer surface damage as indicated by the more gouge productions.

The accumulation of gouge materials on larger roughness fracture surfaces causes a slow drop in permeability.

The fracture surfaces experience larger degradations, but it has small weights of gouge materials on fracture surface after testing under axial dynamic stress.

The reason is that the gouge material transport and mobilization tend to occur in process of dynamic loading.

Therefore, the permeability drops of axial dynamic stress are larger than those of axial static stress.
