Though many damages of quay walls were due to liquefaction of ground, some damages were supposedly caused by tsunami action in addition to earthquake ground motion. Tie wire ruptured and collapse of steel sheet pile wall and aepron happened at the quay wall of Soma Port, possibly affected by the tsunami. Effective stress finite element analysis taking account of earthquake motion and subsequent tsunami under drained condition was conducted in this study, to clarify factors of the collapsed sheet pile type quay wall. As a result, it was found that damage of the sheet pile quay wall of Soma Port was light due to earthquake motion but was extended by subsequent tsunami action. Influence of tsunami action to the sheet pile quay wall was clarified with the analysis taking into account the tsunami water weight on the backfill ground; increase in residual water pressure as tsunami water weight on backfill ground more largely affected unstability of the sheet pile quay wall than vertical load acting on backfill ground surface as that.
