空间数据量的增加和计算机/计算科学的进步提高了使用大规模三维（3D）土壤结构模型进行大规模地震土壤液化分析的可能性。然而，由于 3D 多物理非线性带来的巨大计算成本，这种分析很困难。在本文中，我们提出了一种使用大型 3D 土壤结构模型进行土壤液化分析的有效有限元分析方法。通过结合多种高性能计算方法克服了其巨大的计算成本。作为一个示例应用，我们使用我们的方法对具有网格状地面改良结构的大型 3D 模型进行土壤液化模拟。
The increasing volume of spatial data and advancement of computer/computational science raises the possibility of using large-scale three-dimensional (3D) soil structure models for large-scale seismic soil liquefaction analysis. However, such analysis is difficult due to the huge computational costs incurred by 3D multi-physical non-linearity. In this paper, we present an efficient finite element analysis method for soil liquefaction analysis using large-scale 3D soil structure models. Its huge computational cost was overcome by combining several high performance computing methods. As an example application, we used our method to carry out soil liquefaction simulations of a large-scale 3D model with a grid-form ground improvement structure.
