“…Ari and Misir [31] investigated to determine how well geocell reinforcement works to lessen settlement and increase the bearing capacity of conical and pyramidal shell foundations. As shell foundations, conical and pyramidal geometries were employed, and PLAXIS 3D was used to replicate their actual honeycomb structures.…”

To combat permanent deformation in flexible road pavements and extend lifespan while reducing maintenance costs, an investigated solution "Corrugated Geogrid and Geocell Reinforced Flexible Pavement Base Design" is proposed. It enhances durability by improving inter-layer bonding and increasing the friction coefficient with a Corrugated Imminent Hexagonal Composite Geogrid, boosting pavement bearing capacity. The necessity of this research is the integration of corrugated geogrids and geocells into the design of flexible pavement, in conjunction with a comprehensive evaluation of interlayer shear performance, effectively tackles a range of engineering obstacles and enhances the pavement system's durability, stability, and affordability. Geogrid's corrugated structure resists shoving, offers stabilization, and, combined with Fusion Geoblanket and Perforated Geocell, prevents potholes. Typically, geocellular brace parts are utilized in civil engineering and technical applications, and they are frequently connected to geocellular systems or geocells. These systems are frequently employed in the building of retaining walls, slope protection, erosion control, and soil stabilization. The intended use and product design influence the installation procedures and specific functioning approach. The proposed model prevents permanent pavement failures, ensuring durability, low maintenance, and improved lifespan, assessed through Finite Element Analysis. Thus, the proposed method develops a layout for flexible pavement that's going to prolong its life expectancy and prevent long-term deformation failure.

“…From the range recommended by [33], Poisson's ratio (ʋ) of sand was taken as 0.3. The soilgeocell interface was assumed to be partially rough, with an interface friction factor (δ) of magnitude 0.8 corresponds to the similar value taken by [26]. The detailed numerical analysis test layout of the different properties of sand and different geometric combinations of the geocell used are presented in Table 3.…”

“…The actual honeycomb shape of the geocell rather than square and circular geometry has been modelled by using FEM software to analyse the behaviour of the geocell reinforcement [24][25]. The effectiveness of the geocell reinforced for shell foundation has been investigated by using PLAXIS 3D [26]. Some researchers have given analytical solution to evaluate the settlement and stress propagation in the geocell reinforced soil [27][28].…”

The usage of geocell reinforcement for foundations supported on weak soil has been increased these days. The purposed study uses FEM-based ABAQUS software to analyse the behaviour of square footing supported on geocell reinforced sands subjected to static vertical loading. Numerical analysis was performed to find the optimum combination of the different geometric parameters of the geocell reinforcement. Three distinct types of sands were employed in the study with relative densities of 30%, 50%, and 70%. The geometric parameters of the geocell, such as the placement depth of geocell (u), the width (b), and the height (h) of the geocell, were modified in relation to the footing width (B) to access the optimum combination ratios. The inclusion of the geocell reinforcement increases the load-carrying capacity up to 5-6 times compared to unreinforced sand. The results obtained from the numerical analysis were intended to correlate well with the experimental data available in the literature.

“…Compared to the unreinforced soil, the reinforced case had a load dispersion angle that was about 15% higher and earth pressure cell values that were around 50% to 60% lower. Numerous numerical investigations have been presented to study the behavior of soil reinforced with geocell (Adithan et al, 2021;Ari & Misir, 2021;Latha et al, 2009;Pratap et al, 2022;Sanjei & De Silva, 2016;Yang et al, 2010;Zidan, 2012). To evaluate the behavior of footings on geocells with additional basal geogrid-reinforced soil, comprehensive numerical and experimental studies were conducted by (Dash et al, 2003;A.…”

Geosynthetic reinforcements have become increasingly popular in the last few years for usage in a variety of infrastructure projects because of their advantageous properties. One kind of geosynthetic that is produced as three-dimensional interconnected cells is called geocell. It can be used as a reinforcement to enhance base course behavior by offering lateral confinement, which increases the base course's stiffness and strength while lowering surface permanent deformation. Therefore, this research aims to study the behavior of strip footing rested on a geocell reinforced sand bed experimentally and numerically. In this research, a single geocell, filled with sand, was exposed to a vertical load until reaching failure. The testing process was modeled through the use of PLAXIS 3D numerical software. The effects of using a geocell as a reinforcement on load-bearing capacity and settlement at variable parameters, such as depth of placement, height, and length of reinforcement under axial compression load were studied. The results indicate that using geocell as soil reinforcement leads to a noticeable improvement in the bearing capacity and settlement response of the soil. The recommended geocell layer height, length, and placement depth that give the maximum bearing capacity improvement are presented and discussed. The effect of using geocell as soil reinforcement on the ultimate bearing capacity is estimated by bearing capacity ratio (BCR) and modulus of subgrade reaction (ks).
