The use of programs complexes “Ansys” and “Plaxis 3D” in assessing the influence of the density of sand base on the modulus of deformation

Abstract

The article presents a comparison of the values of the soil deformability characteristics obtained at different densities of the sand base based on the results of laboratory tests3 and the results of computer modeling, using the software systems "ANSYS" and "Plaxis 3D".It was found that for loose sandy soils, at densities of 1.48 – 1.53 g/cm 3, close to experimental values of the deformation modulus were obtained using a three-dimensional finite-element model of polylinear isotropic hardening "PLAS (Miso)," in the program "ANSYS." For average density bases at ρ = 1.55 – 1.66 g/cm3 minimum differences between experimental and numerical values were obtained using the «Plaxis 3D» complex.
