Evolution of Geocells as Sustainable Support to Transportation Infrastructure

“…However, after a certain height, local buckling and straining of geocell walls immobilize the increment in flexural and shear rigidity of the geocells; thus, the loads are not effectively transferred through the geocell layer, leading to a deterioration in performance [23][24][25][28][29][30]. Furthermore, the height of geocells beyond the pressure bulb below the foundation can be considered dormant [31]. The optimum depth of geocells is always less than twice the width of the footing, as validated in most of the available studies [17,18,24,27,32,33].…”

Reinforcement Effect of a Concrete Mat to Prevent Ground Collapses Due to Buried Pipe Damage

“…They discovered that the geocells distribute the underground stress in the lateral direction, thereby reducing the load that is acting on the buried pipes. Tafreshi, et al [25] conducted a plate bearing test by reinforcing a foundation structure and the lower part of the road pavement with several layers of geocells. They [25] discovered that the underground stress was reduced as the number of geocell layers and the elastic modulus of the ground increased.…”

Pancar and AkpJnar [26] studied the ground reinforcement effect using a variety of geosynthetic materials to improve the bearing capacity of the ground under the pavements.…”

Three-Dimensional Discrete-Element Modeling of Geocell-Reinforced Ballast Considering Breakage

“…It is manufactured into various sizes and depths to accommodate different applications. Geocells have been widely used in a variety of infrastructure applications, such as foundations and subbases (Dash, 2012, Yang et al, 2012, Dash and Bora, 2013, Tanyu et al, 2013, Moghaddas Tafreshi, 2015, Oliaei, 2017, slopes (Mehdipour et al, 2013), retaining structures and embankments (Madhavi Latha andRajagopal, 2007, Zhang et al, 2010). All of these studies have shown that using geocells improves the performance of the infrastructure by reinforcing the granular infill materials.…”
