针对洪水和海啸引起的三维自由面流，提出了一种预测岩石、船舶和建筑物残骸等大尺度物体运动的计算方法。为此，提出了一种新的多相模型来处理气、液、固三相。此外，所提出的模型在一个基于高性能计算算法的计算方案中实现，并通过与实验结果的比较验证了该方法。特别是，1）三维模型的开发和一些并行计算方法的引入进行了，和2）进行了多个实验有关的固体物体的自由表面流的运输。

A computational method has been developed to predict the transportation of large-scale objects, such as rocks, ships and debris of buildings, due to the 3D free-surface flows caused by flood and Tsunami. For this purpose, a new multiphase model was proposed to deal with gas, liquid and solid phases. In addition, the proposed model was implemented in a computational scheme based on high-performance computing algorithms and the method was verified by the comparisons with experimental results. In particular, 1) the development of 3D models and the introduction of some parallel computation methods were performed, and 2) multiple experiments were conducted regarding the transportation of solid objects by free surface flows.
