ABSTRACT
A series of light-weight column for receiving the wireless signals to control the stoppage of gas supply are built on the liquefiable ground and their seismic stability should be precisely investigated to prevent the second accident. For the conventional judgment of liquefiable ground, if the soil type of the ground surface is the same, the potential liquefaction of the ground is also the same. In this paper, based on the soil-water coupled finite element method the influence of the depth of the liquefiable layer is taken into consideration and it is found that the seismic stability of the column varies significantly depending on the depth of liquefiable layer even though the embedment depth of the column is the same. Therefore, it is necessary to con-sider the depth of liquefiable layer for the high accuracy analysis.
