Reinforcing soil to improve the mechanical properties of soil for supporting modern infrastructure has gained popularity over the last few decades. For a cellular confinement system, commonly known as geocell, the mechanism of reinforcing soil is different and thus it is important to understand the influence of the state of strain. As some recent studies have shown, cellular confinement systems (CCS) have a significant influence on dynamic performance. CCS not only distributes the load over a wider area with increased layer modulus but also increases the dynamic performance by acting like a layer for a vibration absorber. This advantage of this is particularly seen with machine foundations and railways. Improved vibration absorption also reduced the tendency of surrounding particles’ relative tendency of movement leading to phenomena like lateral spreading, ballast fouling. The effect of the state of strain becomes even more significant when the loads are dynamic. The current paper focuses on a theoretical understanding of the properties of reinforcing material and how they can be related to the short- and long-term performance of load-bearing reinforced granular structures. The elastic dynamic modulus limits the amount of elastic and plastic strain that can develop with each load cycle within CCS. Even if the CCS expansion is elastic, granular material tends to rearrange within itself, making the full elastic recovery of the CCS material difficult. A model has been developed for a rational correlation between the dynamic modulus of CCS and the sporadic vibrations under road embankments.
