“…In the recent past, several model-scale tests have been carried out to understand the behaviour of geocell-reinforced soils under static loads [1][2][3][4][5][6][7][8][9][10][11]. Previous scholars have also reported the use of geocell reinforcement as a cost-effective method for increasing the ultimate bearing capacity and reducing the settlement values of shallow footings.…”

This paper describes the behaviour of a square model footing resting on a geocell-reinforced sand bed subjected to static and repeated loads. The static load tests were conducted to investigate the performance improvement of reinforced soil in terms of bearing capacity and settlement. The repeated load tests were carried out with varying initial static pressures to simulate the structures wherein the live loads change slowly and repeatedly such as oil or water storage tanks do. The ultimate bearing capacity, effect of initial static pressure as well as the number of load cycles without and with the use of geocell reinforcement were the main parameters to be investigated in this study. The results showed that with the provision of geocell reinforcement, the bearing capacity of reinforced soil increased by 2.4 times as compared to unreinforced soil, and the settlement decreased by 68% at the measured settlement level, s/B = 10% (s = settlement of footing, B = width of footing). It has also been observed that the total settlement reduces by 56% in case of geocell-reinforced sand after the application of 20 load cycles. Further, the results show that the total settlement increases at a gradually decreasing rate with an increase in initial static pressure and the number of load cycles.

This paper reports on a series of static and cyclic plate loading tests performed on a weak unreinforced sand bed in a test pit. The weak sand was covered by a 160 mm thick layer comprised of one of three compacted soil types which was either unreinforced or geocell-reinforced. The purpose was to investigate the effects of soil density and grain size as filler materials for the covering layer. The three covering soils were granular with average particle sizes of 2.2 (Soil 1), 6.14 (Soil 2), and 8.47 (Soil 3) mm. Under static loading, the bearing pressure increased on average 23% when the average grain size of the upper, unreinforced, soil layer changed from 2.20 mm to 8.47 mm. The improvement in bearing pressure was about 37% due to the use of a soil-filled geocell but, unlike the unreinforced situation, employing larger soil grains to fill the geocell pockets didn't show significant further improvement. For cyclic loading tests, the maximum settlement reduction by employing a geocell layer was about 50% for Soil 1. Whether loaded statically or cyclically, increasing soil density likely would be more efficient for improving geocell performance than by employing a soil having larger particle sizes.
