Abstract

In this research, a method of obtaining the natural frequencies and natural frequency modes was derived for a soil-water 2-phase system initial value/boundary value problem. Using this method, the natural frequencies and natural frequency modes of the whole soil structure-ground system were calculated for the ground and an embankment constructed on it. The modes extracted included (1) modes in which the ground deformed greatly and (2) modes in which the soil structure deformed greatly. In addition, seismic response analysis was carried out by inputting two types of seismic wave having dominant frequencies close to the natural frequencies corresponding to each mode. The results showed that delayed failure behavior progressing from the ground into the soil structure was exhibited for the seismic waves that targeted (1) and that delayed failure behavior progressing from the soil structure to the ground was exhibited for the seismic waves that targeted (2).
