Abstract
Coastal revetments are required to keep a designated height to protect the hinterland from damage due to tsunami after an earthquake. This paper proposes a new type of steel sheet pile wall which consists of long and short piles. Only long piles are embedded in the non-liquefiable layer, and consequently, the proposed sheet pile wall has many openings between them. Liquefied ground behind the wall allowed to pass through the openings. The wall, therefore, turns aside the pressure from the liquefied ground, and the height of the wall can be secured. In this paper, the applicability of this type of sheet pile wall is discussed based on the results of experimental and numerical studies. Furthermore, simulation method of bending moment of piles to design a specifications of sheet piles is verified.
