17The three-dimensional cellular geoinclusions (e.g. geocells, scrap tires) offer all-around 18 confinement to the granular infill materials, which improves their strength and stiffness. The 19 accurate evaluation of extra confinement offered by these geoinclusions is inevitable for 20 predicting their performance in the field. The existing models to evaluate the additional 21 confinement are based on either plane-strain or axisymmetric stress states. However, these 22 geoinclusions are more likely to be subjected to the three-dimensional stresses in actual 23 practice. This note proposes a semi-empirical model to evaluate the additional confinement 24 provided by cellular geoinclusions under the three-dimensional stress state. The proposed 25 model is successfully validated against the experimental data. A parametric study is conducted 26 to investigate the influence of input parameters on additional confinement. The results reveal 27 that the simplification of the three-dimensional stress state into axisymmetric or plane-strain 28 condition has resulted in inaccurate and unreliable results. The extra confinement offered by 29 the geoinclusion show substantial variation along the intermediate and minor principal stress 30 directions depending on the intermediate principal stress, infill soil and geoinclusion 31 properties. The magnitude of additional confinement increases with an increase in the 32 geoinclusion modulus. The findings are crucial for the accurate assessment of the in-situ 33 performance of three-dimensional cellular geoinclusions. 34 35

Most geotextiles consist of polymers of polyolefin, polyester or polyamide family, which involve environmental problems related to soil pollution. Geotextiles can be used for at least one of the following functions: Separation, reinforcement, filtration, drainage, stabilization, barrier, and erosion protection. Due to the characteristics of high strength, low cost, and easy to use, geotextiles are widely used in geotechnical engineering such as soft foundation reinforcement, slope protection, and drainage system. This paper reviews composition and function of geotextiles in geotechnical engineering. In addition, based on literatures including the most recent data, the discussion turns to recent development of geotextiles, with emphasis on green geotextiles, intelligent geotextiles, and high-performance geotextiles. The present situation of these new geotextiles and their application in geotechnical engineering are reviewed.

“…Beju and Mandal [11] conducted studies on jute geotextile combined with EPS geofoam to protect flexible buried pipes. Coir geocells perform better than coir geotextiles under static loading [12]. Coir geocell was found to be effective in increasing the bearing capacity and reducing the settlement in soft soil [13][14][15].…”

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.
