A STUDY ON THE ADVANCEMENT OF SIMPLE ESTIMATION METHOD FOR THE RESIDUAL DEFORMATION OF QUAY WALLS CONSIDERING THE EFFECT OF LIQUEFACTION DURING EARTHQUAKE

Abstract

 Two dimensional earthquake response analysis is a standard tool for seismic design of quay walls against the level-two earthquake ground motion. However, the computational load of the method is large.
 This study aims at proposing the simple estimation method for the residual deformation of quay walls considering the effect of liquefaction during earthquake. We conducted 5, 600 cases of two-dimensional earthquake response analyses and studied the correlation among the deformation of quay walls and parameters obtained by the one-dimensional earthquake response analyses. We proposed the simple estimation method and verified the accuracy of the proposed method by using past disaster case histories and actual design examples.
