Numerical simulation of CPT in dry and saturated soils using CFD–DEM

Can foam always reduce sandy soil’s permeability? CFD-DEM insights and a gradation-dependent threshold for EPB shield tunneling

Assessing the Potential of Numerical CPTs to Improve the Geotechnical Characterization of Offshore Sites: Case of the Italian Sea

The paper presents the results of large deformation finite element analyses of laboratory and site cone penetration tests (CPTs) in sand. The numerical model implements the Arbitrary Lagrangian-Eulerian formulation and hypoplastic constitutive model to reproduce the soil response. Available laboratory CPTs conducted...

Numerical Investigation of Key Parameters Influencing Stone Column Behavior and the Impact of Column Arrangement on Liquefaction Mitigation in Sandy Soils

One of the most critical challenges faced by geotechnical engineers is soil liquefaction and its associated damage. When saturated soil is subjected to seismic vibrations, its static equilibrium is disrupted due to irregular dynamic forces, leading to the occurrence of liquefaction. This study first validates the n...

Discrete Element Method-Based Mesoscopic Insight into Effect of Soil Mechanical Properties on Shield Tunnel Deformation

Excessive deformations and associated structural defects in urban metro shield tunnels are often observed because of the surcharge load and other disturbances in soft soil areas, threatening the serviceability and even safety of metro systems. However, the quantitative effect of soil mechanical properties on shield tun...

Numerical Analysis of Axisymmetric Consolidation Around Jacked Piles Considering Permeability Reduction in the Disturbed Soil Zone

The installation of jacked piles inevitably disturbs the surrounding soil, leading to a significant reduction in its radial permeability, which in turn retards the dissipation of excess pore water pressure. This study develops an enhanced axisymmetric consolidation theory that explicitly incorporates this installatio...
