Technical standards for port and harbor facilities were revised in 2007 and the deformation of quay-wall during earthquake became the controlled object in seismic safety verification. As an introduction to the establishment of the method for the determination of the allowable deformation for gravity type and sheet pile type quay-wall, this paper shows the statistical analysis on correlation between deformation of quay-wall during earthquake and its damage.
Firstly, we gathered the damage data from the report of past several earthquakes and closely examined the collected data set. Secondly, we surveyed the correlation among the parameters focusing on the failure loss cost and recovery days. Finally, we conducted the multiple regression analyses and proposed the regression equations for the failure loss cost and recovery days according to the deformation of the quay-walls and other design conditions.
