Due to the heterogeneous nature of granular soils and the involvement of many effective parameters in the geotechnical behavior of soil-foundation systems, the accurate prediction of shallow foundation settlements on cohesionless soils is a complex engineering problem. In this study, three new evolutionary-based techniques, including evolutionary polynomial regression (EPR), classical genetic p...

The quasistatic behavior of a simple two-dimensional model of a cohesive powder under isotropic loads is investigated by discrete element simulations. We ignore contact plasticity and focus on the effect of geometry and collective rearrangements on the material behavior. The loose packing states, as assembled and characterized in a previous numerical study [Gilabert, Roux, and Castellanos, Phys...

The highway slope failures are triggered by the rainfall, namely, to create the disaster. However, forecasting the failure of highway slop is difficult because of nonlinear time dependency and seasonal effects, which affect the slope displacements. Starting from the artificial neural networks ANNs since the mid-1990s, an effective means is suggested to judge the stability of slope by forecastin...

Abstract This paper investigates the performance of a single and group laterally loaded barrettes using series numerical models in three-dimensional finite element software. The simulation both directions is verified by comparing predictions to field measurements previously published literature. defines soil wedge around barrette sheared at strain equivalent minimum shear value side or higher a...

The field of infrastructure rehabilitation and development requires a better understanding of soil-structure interactions. The interaction behaviour between soil and structures has mostly been investigated through theoretical and/or numerical analysis. This paper presents a series of experiments performed on an intermediate-scale physical model made of an instrumented silo. In contrast to most ...

Displacement finite element analysis is performed for a cone-penetration test in cohesionless soils. By modelling finite strain in the soil and large scale sliding at the penetrometer–soil interface, a more realistic penetration process is simulated in which the penetrometer is assumed to be rigid and the soil is assumed to be an elastic-perfect-plastic continuum obeying the Mohr–Coulomb criter...
