Item Comparative Study for Performance of Soil Bed Reinforced with Jute and Sisal Geocells as Alternatives to HDPE Geocells(Springer Science and Business Media Deutschland GmbH, 2020) Kolathayar, S.; Sowmya, S.; Priyanka, E.This paper presents the performance of soil bed reinforced with jute and sisal geocells compared to HDPE geocells. The bearing pressure–settlement behaviour of the soil bed reinforced with natural geocells, soil bed reinforced with HDPE geocells and of unreinforced soil bed are discussed. The soil bed reinforced with jute cell and sisal cell showed a uniform increase in the settlement with increase in the applied pressure. The soil reinforced with HDPE geocell, however, showed a sudden rise in the settlement at higher pressure. Sisal mat used for developing the geocell was found to have greater tensile strength, followed by jute mat over HDPE material. Soil reinforced with sisal cells could bear larger stresses at lower strain compared to HDPE geocell. Analytical studies on jute and sisal geocells also were carried out considering the load transfer mechanism of geocell-reinforced soil. © 2020, Springer Nature Switzerland AG.Item Model Footing Tests and Analytical Studies on Clayey Soil Bed Reinforced with Coconut Shell Mat(Springer Science and Business Media Deutschland GmbH, 2022) Kolathayar, S.; Gadekari, R.S.The cellular confinement systems are becoming popular in ground improvement because of their efficiency in improving the bearing capacity of soil due to the lateral confinement effect. The commercially available geocells are made from polymer materials and they are costly. This study presents the performance evaluation of coconut shell mat as a cellular confinement system in clayey soil. It is the first of its kind application of coconut shells for soil reinforcement through a lateral confinement mechanism. This soil reinforcement system using coconut shells is termed “Geococoshell” by the authors. A series of model plate load tests were conducted on unreinforced soil, soil reinforced with High-Density Polyethylene (HDPE) geocells, and soil reinforced with coconut shell mats to evaluate the performance of coconut shell mat reinforced soil bed. The results of the experiments showed that coconut shells reinforced clayey soil improved bearing capacity up to 1.5 times compared to HDPE geocell reinforced clayey bed. The effect of different patterns of placing coconut shell mat was also studied and discussed in the paper. The analytical studies have been conducted considering the reinforcement mechanisms of coconut shell mat embedded in the soil bed. © 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
