3D Numerical Modeling of Rigid Inclusion-Improved Soft Soils Under Monotonic and Cyclic Loading—Case of a Small-Scale Laboratory Experiment

This paper is based on small-scale laboratory tests (1:10) of a rigid inclusion-improved soil under normal gravity. A low area improvement ratio (2.4%) monotonic and cyclic loading was used. 3D numerical calculations are performed to model these tests. The proposed modeling by the finite element method (FEM) using ABAQUS software. representative elementary volume suggested for reducing calculation time. hypoplastic constitutive (HYP model) applied load transfer platform (LTP). total three geometrical configuration cases experimental numerically considered including slab over mattress 100 mm reinforced soil, 50 soil. results compared data previous Houda. response systems shown in terms arching settlements. decrease pile efficacy cumulative settlements exhibited. HYP allows better simulate mechanisms inside LTP than CYsoil used Houda’s research work. good concordance between obtained.
