Numerical Analysis of the Earth Pressure during Earthquake on the Gravity Type Quay Wall

摘要

The dynamic response of gravity type of quay wall was analyzed bymeans of Finite Element Method (FEM) with a focus on the inter actionbetween caisson and backfill ground. First;;the fundamental vibrationproperty of the quay wall is examined;;and the FEM model is calibrated,so as to simulate the observed behavior in a micro tremor measurement.Next;;the behavior of earth pressure on caisson from backfill ground inthe course of liquefaction is analyzed;;and the significant effect ofliquefaction on the stability of quay wall is indicated through thecomparative examination of the analytical results.
