| Research Abstract |
Propagation of fault displacement through subsurface layer due to basement-fault movement was examined. 3D morphology of shear bands was shown by numerical analysis. The process and the mechanism of the development of shear bands were analyzed in terms of stress inside the subsurface layer and the soil particle structure. The numerical simulation result of Nojima fault showed resemblance to the results of observations. It was shown that there is a possibility that the damage to structures due to fault displacement is mitigated by using materials of large grain size.
