Highlighting the Change of the Dynamic Response to Discrete Variation of Soil Stiffness in the Process of Dynamic Compaction with Roller Compactors Based on Linear Rheological Modeling

摘要

The paper presents the dynamic response in motion and stress transmitted to the soil to rotating inertial dynamic excitations, for each layer of soil with specific stiffness. Upon repeated passages on the same layer of soil, there will be taken into account the new rigidities that change the dynamic response called "successive transition" within the linear - elastic limit, up to the ultimate the achievement of the last end state of deformability. Parametric variation curves are specific to certain regularities families expressing multiple correlations, useful for assessing the degree of compaction by vibration of natural soils, by highlighting the movement of resonance points after each pass on the same layer of soil.
