Critical Overview of Reinforcing Sand Using Geocell for Shallow Foundation
Geocells are the non-planar form of geosynthetics which is used to reinforce weaker soils. These are interconnected cells which forms like a mattress that confines the soil within the individual cells, enabling the soil–geocell system to bear higher loads with minimum settlement values. Several parameters that affect the performance of the geocell are—height of the geocell, pocket size of the cell, characteristics of the infill material, stiffness of the geocell, and location of placement. Researchers have conducted experimental as well as numerical analysis to understand the working mechanism of the geocells under static as well as dynamic loading. Finite element modeling has been used to simulate the behavior of these materials in various applications such as in embankments and foundations. It has been found that the inclusion of geocells can substantially improve the bearing capacity of soil to 7 times that of unreinforced soil and considerably reduce the settlement to optimum values. The objective of the paper is to identify the optimum values of various parameters of geocell which gives suitable results under static loading conditions. The optimum values for u/B and h/B were found to vary between 0.05–0.1 and 0.4–2, respectively. Moreover, with the addition of geogrid at the base of geocell mattress, further improvements in load-bearing capacity of the soil can be obtained.
