The Role of Seepage Flow Rate and Deviatoric Stress on the Onset and Progression of Internal Stabili stress states that the soil is subject to being one of the determinant factors. This preliminary study investigates under small-scale laboratory conditions, the influence of seepage flow under complex stress states on the behaviour of a gap-graded soil including change in volume, permeability, stre

Assessment of Internal Stability of Granular Soils by Means of Theoretical and Laboratory Methodsns of semi-empirical, theoretical and experimental methods; the assessment of internal stability of a soil using the available semi-empirical criteria can provide different results. In the paper, in order to verify and validate two methods recently proposed by the authors (Moraci et al. ., .; Moraci

New Apparatus for Assessing Soil Suffusion Susceptibility Under Two Flow Directions can induce important modifications in the hydraulic and mechanical characteristics of the soil in different flow directions. Thus, to ensure the safety assessment of hydraulic earth structures, the experimental models need to match the reality of the body of dikes or dams with horizontal flow. In t

Viewing Fluid Flow Inside a Granular Mediuml erosion in filter materials for embankment dams. The laboratory-based experiments utilise an optical approach where glass particles are used in place of soil, and optically matched oil is used in place of water. The refractive index matching of the fluid and solid enables a two-dimensional “slice”

Effects of Void Ratio and Hydraulic Gradient on Permeability and Suffusion of Glacial Till Cores other types of materials, as reported by Sherard (.). Garner and Fannin (.) indicated that internal erosion initiates when an unfavorable combination of soil material, stress conditions and hydraulic load occur. A laboratory program, carried out at Luleå University of Technology (LTU), aims to stud

Finite Element Analysis of Internal Erosion Effect on the Stability of Dikesconsisting of erosion equations, mixture flow equations and stress equilibrium equations, is solved numerically by the finite element method using COMSOL Multiphysics. The shear strength reduction technique is used to analyze the stability of a dike taking into account the effect of internal erosion

Modelling of Backward Erosion Piping in Two- and Three- Dimensional Domainsity of numerical models developed for predicting piping are two-dimensional. This study presents finite element models for backward erosion piping computations in both two- and three-dimensional domains. Analyses results indicate that the degree of concentration of flow in three-dimensional models i
