    Numerical Study on Bearing Capacity Estimation of Circular Footing on Sand Reinforced with Sisal Geotextile
    (Springer Science and Business Media Deutschland GmbH, 2025) Jena, S.; Khatri, V.N.; Nainegali, L.
    This paper presents a study on estimating the bearing capacity of shallow circular footings on sand. In this regard, finite element analysis is conducted, assuming that the sand follows Bolton’s model with a relative density of 75%. Initially, the bearing capacity is determined for unreinforced sand conditions, followed by the placement of geotextile at different depths. The results indicate a significant increase in the ultimate bearing capacity of the footing, up to 2.68 times, compared to the unreinforced case, precisely when the geotextile is placed at a depth of 0.25 times the footing diameter. These findings suggest that sisal geotextile can effectively serve as a reinforcement material for addressing various temporary foundation-related problems. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

    Bearing ratio behaviour of sisal geotextile reinforced fly ash overlying clay
    (Taylor and Francis Ltd., 2025) Jena, S.; Khatri, V.N.; Nainegali, L.
    The paper examines the bearing ratio behaviour of sisal geotextile reinforced fly ash over clay. It also evaluates the effects of alkali treatment and emulsion coating of the geotextile on the bearing ratio at optimal placement depths. Results show that using one, two, and three layers of untreated geotextile increased the CBR by 19.6%, 55%, and 78% at different placement depths (1.5B, 1B, and 0.5B), where B is the plunger diameter. Alkali-treated and emulsion-coated geotextiles increased the CBR by 24.6% and 15.6%, respectively. However, soaking reduced the CBR by 76.6%, with the greatest decrease observed in triple-reinforced alkali-treated samples. Punching tests and morphological analyses supported the study outcomes. A numerical study of a pavement section, based on the experimental results, recommends sisal geotextile for rural roads using load equivalency factors and the structural number approach. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
