In recent years, civil engineers have started to use discrete-element modelling simulate large-scale soil volumes thanks technological improvements in both hardware and software. However, existing procedures prepare ‘representative elementary volumes’ (REV) are unsatisfactory terms of computational cost sample homogeneity. this work, a simple but efficient procedure initialise models is presented. Periodic cells first generated with sufficient number particles (enough consider the cell an...
Low-pressure injection of nanosilica aqueous suspensions is often adopted to either waterproof or increase the liquefaction resistance granular soils. The basic principle behind this ground improvement technique consists in filling soil pores with a low-viscosity fluid that changes its consistency time, first into gel, then solid. From an application point view, simulation time-dependent permeation process crucial relate situ distance covered by grout operational parameters. A comprehensive...
Soil layering modifies cone penetration measurements when the is close to layer boundaries. Transition zone and thin-layer effects appear, complicating interpretation. To help identify mechanisms underlying transition effects, several series of realistic simulations in layered soils are presented. Cone tests simulated using fully coupled hydromechanical models solved with particle finite-element method. A constitutive model capable representing flow liquefaction employed explore effect...
Permeation grouting – injections at low-pressure values of either microfine cements or chemical products is frequently adopted to increase the mechanical/hydraulic properties soils, and standard design approaches are currently empirical based on simplified analytical solutions. In this paper, some fundamental hypotheses these solutions discussed by carrying out a campaign finite-element numerical analyses, in which injection phase water-saturated soil analysed, Newtonian rheology for grout...
Abstract Anchored wire meshes are commonly adopted to stabilize potentially unstable soil slopes. This reinforcement technique, employed either as an active or a passive anchoring system, is designed according ultimate limit state approaches. In this paper, interaction model, useful for the design of anchored meshes, proposed. The model based on results series 3D large displacement finite element numerical analyses, in which mesh mechanical behaviour modelled elastic elastic–plastic...
