New methods of evaluating the seismic coefficients for earthquake resistant design of quay walls against the level-one earthquake ground motion were introduced in the technical standards for port and harbour facilities revised in 2007. The methods are for caisson type and sheet pile type quay walls, and those for other structural types have not been examined yet. In this paper, we examined and proposed the methods of evaluating the seismic coefficients for cantilever sheet pile quay walls. The proposed methods are in consistent with those by the previous study and take into consideration of the effect of frequency characteristic and duration time of earthquake ground motion on the deformation quay walls.
