Abstract
Water-level difference induced by tsunami generates seepage flow in a mound of breakwaters. It has been pointed out that the flow weakens a bearing capacity of a mound. The present report describes bearing capacity properties of a mound under seepage flow, by using centrifuge model tests and finite element method analyses. Two types of model tests were conducted in the study: horizontal load tests and combined tests with horizontal load and seepage flow. According to the model tests, seepage flow resulted in a slight decrease of a bearing capacity. In addition, it was confirmed that finite element method analyses could simulate the model tests, and a bearing capacity was also reduced by seepage flow in a commonly-used breakwater as well.
