Abstract: In this study, an analysis of soil–retaining wall dynamic interaction is conducted using three-dimensional discrete-element method (DEM) simulations. Soil grains are treated as rigid spherical particles that are allowed ...

Abstract: Fine-particle migration and associated internal erosion are major concerns for dam safety. Granular filters are used to prevent fine-particle migration, and several empirical models have been introduced for the design of ...

Abstract: A very limited number of computational studies have been presented for the analysis of the response of saturated granular soils to multidirectional shaking despite it being the realistic mode of loading that resembles an ...

Abstract: A three-dimensional transient fully coupled fluid-particle model is utilized to simulate flood-induced piping under river levees and taking into account the effects of soil-fluid-structure interactions. The porous soil ...

Abstract: A coupled hydromechanical model was used to analyze the mesoscale pore fluid flow and microscale solid phase deformation of saturated granular soils. The fluid motion was idealized using averaged Navier–Stokes equations, ...
