Plate Load Tests of Multi-Layered Geocell Reinforced Bed Considering Embedment Depth of Footing

Evolution of Geocells as Sustainable Support to Transportation Infrastructure

“…The soil cushion between the footing and the geocell layer and in between two geocell layers enables the development of effective friction at geocell-soil interfaces. The soil cushion, along with the geocell-reinforced soil composite, behaves as a rigid system, which enables the distribution of the load over a wider area of the underlying soil [13,24,[26][27][28][29]50]. The load dispersion mechanism offered by the sand cushion is evident from the measured strains along the height of the geocell wall.…”

“…Figure 9 shows a schematic diagram of a foundation reinforced with multiple geocell layers. An increase in the number of geocell layers results in improved performance because of increased soil-geocell contact area, which can contribute to significantly higher frictional resistance, enhanced confinement effect, and its homogeneous stress distribution below the foundation [49,50]. Furthermore, with more geocell layers, the volume of soil under the reinforcement effect increases, resulting in an overall increase in stiffness [16,19].…”

“…Furthermore, with more geocell layers, the volume of soil under the reinforcement effect increases, resulting in an overall increase in stiffness [16,19]. With multiple geocell layers below the loaded area, the entire pressure bulb within the ground can be encased within the geocell reinforcement, thus completely arresting the lateral and vertical deformations [31,50]. However, the installation of multiple geocell layers requires deeper excavation and filling, which significantly increases the cost of the project.…”

“…As the number of geocell layer increases, the energy absorbance characteristics offered by them under cyclic loading increase, thus reducing the magnitude of stresses and shocks transferred to the underlying soil [47]. However, unlike static loading conditions where the rate of improvement was higher at higher settlement levels, it became insignificant at higher number of load cycles for heavily reinforced systems during cyclic loading conditions [26,42,48,50,53].…”
