A STUDY ON IMPROVEMENT OF THE CROSS SECTION SETTING METHOD OF OPEN TYPE WHARVES AGAINST LEVEL-TWO EARTHQUAKE GROUND MOTION

Abstract

 Authors proposed the cross section setting method for the design of open type wharves by use of the optimization algorithm in the past research. However, past research was conducted only on the large impedance contrast ground condition. This study first discusses the applicability of the proposed method to the low impedance contrast ground condition. Next, we discussed the soil spring model to improve the accuracy of the proposed method for thick liquefaction soil layers.
