Vibration tests of model anchored sheet-pile walls with a rigid, flexible and fixed anchor wall in dry sand were performed using by a shakng table, in order to investigate the earthquake resistance of anchor walls. Results of the tests are summerized as follows.
1.The sheet-pile wall and sand backfill near the wall behave as one mass during vibration and the force caused by the vibrating mass act on the anchor as the anchor pull.
2.The anchor pull of movable anchor during vibration is smaller than that of fixed anchor.
3.The forward movement of anchor wall during vibration is larger than that of static loading test. This large movement of anchor wall is caused by remarkable decrease of the stiffness of sand near the anchor wall and also it is affected by the number of cycles of forced vibration.
