Abstract
In the Great East Japan Earthquake in 2011, a large number of tsunami drifts increase the devastating damage. In order to develop the computational method that can deal with many tsunami drifts, a multiphase model (MICS) was improved so that it can take account of the collisions among drifts, buildings and ground surfaces. The numerical experiments were conducted with the present computatinal method. As a result, it was shown that the present method allows us to calculate many floating objects transported among non-uniform ground surface and the debris control structures. In addition, fluid forces acting on structures were estimated. Finally, the efficiency of the present parallel computations was discussed.
