Dynamic Properties of Soil Cements for Numerical Modelling of the Foundation’s Basis Transformed under the Technology of Deep Soil Mixing: A Determination Method

This research investigates the mechanical properties of soil-cement specimens ranging from ultrasmall to large values shear strain at dynamic loading. The nonlinear behavior soil cement exposed loading in a wide range changing strains was examined on basis two models. All were collected under an existing building and modified with deep mixing (DSM.). Soil-cement samples using low-amplitude oscillations resonant column triaxial compression method. Additionally, stress–strain state for footings loading, approximation stiffness damping coefficient analyzed. Dependencies resilient elastic models Ramberg–Osgood Hardin–Drnevich are proposed application. Results reveal that empirical graphs dependency stiffness–shear based various methods exhibited distinctive S-shape decreased stiffness. reduced by 50% maximal value 10?3 decimal order. method presented this study enables drawing change damping–shear where changes strains. normalized modulus shearing could be obtained can used preliminary calculations structures footing mathematical modelling or when field data site investigation not available.
