Physical Model Tests on Reinforced Loess Foundation Model Under Wetting and Loading
Published 2025-07-01“…When the load reached 120 kPa, the deformation was wetted gradually under this load. Finite element numerical simulations were conducted to model the physical tests and analyze the optimal parameters and arrangements of reinforcement layers for reinforced loess foundations.Results and DiscussionsThe results showed that, compared to the pure loess foundation, the inclusion of geogrids within the collapsible loess foundation significantly improves the stress diffusion effect of the foundation and thus reduces the internal earth pressures and surface settlements within the width of the footing. …”
