Abstract
The reinforced earth method has been used in many land construction works, based on its high seismic performance. On the other hand, it has not been applied to the construction of port facilities. Our group studies how to apply this method to sheet-pile quay wall, and it can become a cost-effective quay wall, compared with the conventional one. In this study, a series of centrifuge model tests were conducted under a centrifugal acceleration of 50g by changing length, height, and number of reinforcing geogrids connected with sheet piles. Displacements of sheet pile and ground, tension forces of geogrid, and bending moments of sheet pile during seismic motions were discussed in the paper. The results showed high performance of this method, and the specification of a sheet pile can be reduced because of its low bending moment.
