ANALYSIS OF DEFORMATION IN FISHERY HARBOR QUAY WALL, WHICH WERE DAMAGED DURING 1994 EAST OFF HOKKAIDO EARTHQUAKE

Abstract

On October 4, 1994, an earthquake of magnitude 8.1 occurred at east off Hokkaido. Many Port structures and fishery harbor structures in east Hokkaido were damaged. Therefore, two dimensional effective stress analyses are conducted for quay wall based on the data in there. This is analysis for -4.0m quay wall in Shibetu fishery harbor that was damaged by the earthquake.The results of the effective stress analysis of quay wall indicate that a fundamental pattern of the deformation of the quay wall is reasonably simulated by the present approach.
