| A bridge abutment, which is a type of retaining structures, needs designing against earth pressure from the backfilling. In addition to earth pressure from the backfilling during an earthquake, an abutment that is constructed on the liquefiable ground may be subjected to lateral movement of backfilling due to liquefaction. However, there remain many uncertaties regarding how earth pressure and earthquake behavior affect abutments through ground liquefaction-induced movement. Therefore, the authors conducted dynamic centrifuge tests for the purpose of studying how earth pressure affects bridge abutments. In this paper, we report the results of an experimental study, in which we focus on earth pressure on bridge abutments that occurs during an earthquake as well as earth pressure that occurs with ground movement. |
