STUDY OF THE IMPROVEMENT OF ACCURACY FOR THE 2-DIMENTIONAL EFFECTIVE STRESS ANALYSIS METHOD

Abstract

The influences of many factors on the accuracy of the damage prediction have been evaluated for a two-dimensional effective stress analysis program code: FLIP. Although many improved numerical models for more precise prediction have been proposed, the influences of those improved models varied with the difference of structural type and situation. This study was carried out to verify th accuracy ofthe seismic damage estimation for various types of quay wall on the liquefiable ground by the FLIP code with all these improved models simultaneously.
Through the seismic damage analyses of sheet pilequaywall, gravity quaywall and piled pier constructed on the liquefiable ground, it was observed that the improved models work well not only for the structure in which the conventional model had worked well, but also for the structure in which the conventional model cannot work.
