Abstract
In the initial report on a tsunami disaster in the Great East Japan Earthquake, a scouring at a joint between caissons was listed up as one of the causes of failure of a composite breakwater. Although posterior experiments proved that it was not crucial mechanism, a flow field behind a caisson was not investigated in detail in those experiments. In this study, to clarify a complicated flow field driven by jet from a joint and tsunami overflow, we carry out a numerical simulation by using a numerical wave flume based on an accurate particle method. Especially, we focus on a three-dimensional flow structure around a joint between caissons.
