In this study, I developed a multi-scale numerical method for the deformation of grains-water coupling system based on a nonlinear homogenization method. Moreover, we carried out the numerical simulation of the grain-water coupling problems to investigate the strength and deformation characteristics. At first, a governing equation of the grains-water coupling deformation problems in the saturated state was formulated. Next, I developed the original simulation program for the problems. At the same time, I carried out the experiment and visualization of the deformation behavior of grains-liquid coupling systems to grasp micro-mechanical phenomena. As the results in this study, I was able to simulate the mechanical behavior of the saturated grains-water system.

在这项研究中，我开发了一种基于非线性均质化方法的谷物水偶联系统变形的多尺度数值方法。此外，我们对谷物水耦合问题进行了数值模拟，以研究强度和变形特性。最初，制定了饱和状态下谷物 - 水耦合变形问题的管理方程。接下来，我制定了针对问题的原始仿真程序。同时，我对谷物液耦合系统的变形行为进行了实验和可视化，以掌握微型机械现象。作为这项研究的结果，我能够模拟饱和谷物水系统的机械行为。
