论文摘要
在本文中,我们描述了一种结合土壤力学(饱和沉积物),流体力学(海水或空气)和固体力学(结构)的土壤流体结构相互作用模型。该配方结合了材料点方法,该方法将多孔介质和结构的大变形建模与隐式连续富集欧拉(Eulerian)建模,该方法对复杂的流体流进行了建模。我们验证该模型并模拟地震引起的海底滑坡的整个过程。我们表明,该模型捕获了饱和沉积物,海水和结构之间的复杂相互作用,因此我们可以使用该模型来估计潜在海底滑坡对离岸结构的影响。
In this paper, we describe a soil-fluid-structure interaction model that combines soil mechanics (saturated sediments), fluid mechanics (seawater or air), and solid mechanics (structures). The formulation combines the Material Point Method, which models large deformation of the porous media and the structure, with the Implicit Continuous-fluid Eulerian, which models complex fluid flows. We validate the model and simulate the whole process of earthquake-induced submarine landslides. We show that this model captures complex interactions between saturated sediment, seawater, and structure, so we can use the model to estimate the impact of potential submarine landslides on offshore structures.
