EVALUATION OF PERFORMANCE LEVEL OF REVETMENTS

Abstract

One of performance requirements for revetments should be determined in terms of vertical displacement because revetments should prevent wave overtopping. This study aims at evaluating the performance level of current revetments designed with the present design code. We collected datum of revetments constructed all over Japan and evaluated allowable vertical displacements considering the allowable wave overtopping rate for each revetment. Frequency distribution of evaluated allowable vertical displacements of revetments is presented. We then compared the allowable vertical displacements for revetments with allowable lateral displacements for quay walls by using the results of earthquake response analyses.
