摘要

The cellular reinforcing system, commercially known as the geocell, is widely appreciated and used for its efficiency in improving performances of various geotechnical applications. At present, it is mostly available in synthetic forms; however, with increasing environmental awareness and emphasis on sustainability, engineers are strongly promoting the use of natural fibres, such as jute, sisal, coir etc. as the raw material. Following this trend, the present study developed a natural-fibre-based geocell, termed as “jutecell”, in the laboratory. It is fabricated by stitching jute geotextile (JGT) strips into a mattress using an ordinary sewing machine. Prior to physical testing, a numerical study on jutecell-reinforced foundations is performed in PLAXIS 3D, simulating the intended laboratory configurations. The study considers a series of analyses on single, double, and triple layers of jutecell mattresses with different configurations. Performance is evaluated in layered soils with a “loose-over-dense” formation, where the upper stratum is reinforced with the jutecell. The results indicate that the jutecell enhances bearing capacity and reduces foundation deformations compared to corresponding unreinforced beds. The study observes a 2.5–3.0-fold improvement in bearing pressures, highlighting the potential of the jutecell as a sustainable geo-reinforcement solution using natural fibres.
