Abstract
The effects of shape of geogrid-reinforced counterweight fill on seismic stability of existing river levee located on liquefiable ground were investigated. In this study, shape of the counterweight fills as well as its relationship with geological conditions such as thickness of the liquefiable layer were investigated by performed shaking table tests. As a result, it was confirmed that placement of counterweight fill is an effective method for improving the seismic stability of existing levees on liquefiable ground, and is effective in geological conditions where the thickness of the liquefiable layer is thin. Even if the volume is the same, the effects of liquefaction countermeasures depend on the shape of the counterweight fill. Therefore, it is better to place the counterweight fill as to cover the existing levee.
