ANALYSIS ON THE EFFECT OF WIDENING WORKS OF BREAKWATERS AGAINST TSUNAMI-INDUCED SEEPAGE FLOW IN THE RUBBLE MOUND

Abstract

 The study aims at confirming the effect of widening works for caisson type breakwaters against tsunami-induced seepage flow in the rubble mound. The study compares the calculated baring force of rubble mound by the Geotechnical Finite Element Analysis (GeoFem) and that by the Simplified Bishop Method stipulated by the Technical Standard for Port and Harbor Facilities. The result shows a strong correlation between the two.
