Abstract

It is important to develop the Solid-Gas-Liquid coupling system for analyzing the mechanism of failure of structures on land by Tsunami. At first, the numeric wave tank, whose name is CADMAS-SURF/3D, is improved to correspond to two phase incompressible fluid. This two phase flow tank is applied to the impulsive wave pressure problem. As a result, it is confirmed that a numeric noise, which is called Spike Noise, is removed and the accuracy of the result is good agreement with the single phase model. Next step, the coupling system with DEM method is developed. The wall destruction test by fluid is conducted. The appearance of the wall destruction adjusted the large-scale experiment, and the validity of three phase coupling system is confirmed qualitatively.
