Elasticity Coefficient Calculation for the Active Volume of Soil Layer Compacted by a Vibratory Road Roller

Abstract

article discusses process of evaluation for the stiffness (elasticity coefficient) of soil mass of special shape being determined by stress distribution caused by surface force.  It is important for model description of interaction between road roller and soil during vibratory compaction in the framework of lumped parameters approach. The main part of the modelling procedure for dynamic deformation during compaction is a choice of initial stress distribution. The problem of calculation of the soil mass stiffness under assumption of Westergaard normal stress distribution is solved and recommendation further application of the results for numeric experiments are done.
