Comparative Analysis
of the Voigt–Kelvin and Maxwell Models
in the Compaction by Vibration Process
Cornelia-Florentina Dobrescu
Abstract The dynamic compaction of the soil is made with cylindrical vibratory
equipment called vibratory compact rollers. The compaction process consists of
transmitting the static force corresponding to the weight of the roll as well as the
dynamic force generated by a vibrator placed inside the roller. By the combined effect
of static pressure and simultaneous transmission of the dynamic force on the soil, it
is achieved the compaction of the soil layers over their entire height. The final effect
of the compaction process consists of the increase in the soil density and reduce the
reduction of the holes so that the conditions for increasing the mechanical strength
and the stability of the foundation of the road construction are created. In this context,
the variety of the physical and mechanical parameters of soil requires the analysis
of the compatibility of the significant rheological models with the dynamic action
capacity of the vibratory rollers.
1 Introduction
The specified problematics can be addressed by the comparative analysis of soil
behavior at compaction on the basis of two significant models, namely the Voigt–
Kelvin model and the Maxwell model [1–5]. These models describe two distinct
behaviors such as the predominantly elastic character with reduced viscosity represented by the Voigt–Kelvin rheological scheme or the predominantly viscous character with reduced elasticity represented by the Maxwell rheological schematization
[6–8].
As a result of the researches made, this article will present the results of the
dynamic behavior modeling exemplified by the evaluation of the maximum dynamic
force transmitted to the land for the two significant rheological models [9–11].
