Comparison between Theory and Experiment for the Dry Density and Shear Stress Variations with the different Depths (groundwater level variations)

Abstract

Comparison between Theory (Numerical simulation by the PLAXIS 3D – Finite element method) and Experiment measurement by the Viet Nam Standard “TCVN 4195:2012; TCVN 4199:1995” for the Dry Density and Shear Stress Variations with the different Depths (groundwater level variations) were shown clearly with the particular process. Results show the Dry unit weight (density) increases gradually with the increase of different depths. The maximum deviation of the dry unit weight (dry density) and Shear Stress according to the constant loading (P) at the different depths, which included in the dry density (γk) value of 16.26 kN/m2 and shear stress (τmax) 72.7 kN/m2 at 4.3m; whereas shear stress (τmax) 41.6 kN/m2; 27.1 kN/m2; 91.8 kN/m2; 98.2 kN/m2; 82.9 kN/m2 at 7.0m; 18.0m; 27.0m; 30.3m, and 39.6m; respectively. Results show the small deviation together, but some values presented changing remarkably. So research results enough reliable reference in the geotechnical engineering and researchers in the future.
