The boundary conditions imposed on the geocell pack in a laboratory test governs the deformation throughout the pack and has to be taken into account when interpreting the test results. In recent years, horizontal plate anchors have been reinforced with geosynthetic materials. But in sometimes the increase of these parameters (anchors size, embedment depth, relative density of soil) is not possible in terms of feasibility, labor and cost. Geocell products were developed in the late 1970s and early 1980s. Based on the experimental studies, an analytical model was also developed to estimate the load carrying capacity of the soft clay bed reinforced with geocell and combination of geocell and geogrid.
