When planning to construct structures, it is desirable to select an area not to be affected by fault induced permanent ground deformations. But there are inevitable cases with railway structures, so it is necessary to consider the effect of fault induced permanent ground deformations on the structural behavior. Therefore, in this paper, the difference of the growing process of the shear zone with and without foundation was investigated through scaled static experiment. In the test, bottom of the layered sand was partially dislocated using a hydraulic jack to simulate a dip slip fault. As a result, it was found that the shear zone tends to grow up to the ground surface while avoiding the foundation.
