Study of P waves through layered and fault geometries, using the two-dimensional model technique

[摘要] The two dimensional seismic scale model technique was used to investigate high frequency wave propagation trough fault and layered geometries. These structures were simulated, using one or more different elastic media. The reflection method was used considering logitudinal wave propagation and the experimental data obtained were then analyzed. Several different cases were studied.In the layered cases,thin layers of wax were used between plexiglass sheets. These thin wax layers produce the necessary contrast of the acoustical impedances,so that reflections as well as transmitted energy could be produced. Three fault geometries were also studied. These were obtained by varying the simulated fault plane between 70 and 110 degrees. The frequency used throughout this experiment is about 630 times greater than that used in the field.
