Abstract
On the basis of the investigation results of the damaged embankments in farm land, the classification of the damage pattern has been presented. It is found that one of the cause of damage is the water-level in the embankment uprising, and the other is the seismic force acting on the mass of embankment. The trial application of the limit state design method to the design for the embankments in farm land is described. The reserve capacity in excess of the required capacity represents the safety margin. The reserve capacity on the seismic deformation for the embankment is calculated by the Newmark method. It may be possible to introduce the performance-based design on the deformation for the embankment in farm land.
