Geotextiles are commercially made from synthetic fibres and have been used to enhance bearing capacity and to reduce the settlement of weak soil foundations. Several efforts have been made to investigate the possibility of using bio-based geotextiles for addressing environmental issues. This paper attempts to review previous studies on the bearing capacity improvement of soils reinforced with bio-based geotextiles under a vertical static load. The bearing capacity of the unreinforced foundation was used as a reference to illustrate the role of bio-based geotextiles in bearing capacity improvement. The effects of first geotextile depth to footing width ratio (d/B), geotextile spacing to footing width ratio (S/B), geotextile length to footing width ratio (L/B) and the number of reinforcement layers (N) on the bearing capacity were reviewed and presented in this paper. The optimum d/B ratio, which resulted in the maximum ultimate bearing capacity, was found to be in the range of 0.25–0.4. The optimum S/B ratio was in the range of 0.12–0.5. The most suitable L/B ratio, which resulted in better soil performance against vertical pressure, was about 3. Besides, the optimum number of layers providing the maximum bearing capacity was about three This article is useful as a guideline for a practical design and future research on the application of the natural geotextiles to improve the short-term bearing capacity of weak soil foundations in various sustainable geotechnical applications.

天然有限寿命土工布加固技术可持续提高土壤承载力的研究进展

土工织物是由合成纤维商业制成的,已被用于增强承载能力并减少软土地基的沉降。为了研究使用生物基土工布解决环境问题的可能性,已经做出了一些努力。本文试图回顾一下以前在垂直静态载荷下使用生物基土工织物加固的土壤的承载能力的研究。未增强基础的承载力用作参考,以说明生物基土工布在改善承载力中的作用。第一土工布深度与基脚宽度之比(d / B),土工布间距与基脚宽度之比(S / B),本文对土工布的长度与基脚宽度之比(L / B)和增强层数(N)对承载力进行了综述并进行了介绍。导致最大极限承载力的最佳d / B比在0.25-0.4范围内。最佳S / B比在0.12–0.5的范围内。最合适的L / B比约为3,可在垂直压力下产生更好的土壤性能。此外,提供最大承载力的最佳层数约为3。本文可作为实用设计和将来的指导天然土工布在各种可持续岩土工程应用中提高软弱地基的短期承载力的研究。导致最大极限承载力的范围是0.25-0.4。最佳S / B比在0.12–0.5的范围内。最合适的L / B比约为3,可在垂直压力下产生更好的土壤性能。此外,提供最大承载力的最佳层数约为3。本文可作为实用设计和将来的指导天然土工布在各种可持续岩土工程应用中提高软弱地基的短期承载力的研究。导致最大极限承载力的范围是0.25-0.4。最佳S / B比在0.12–0.5的范围内。最合适的L / B比约为3,可在垂直压力下产生更好的土壤性能。此外,提供最大承载力的最佳层数约为3。本文可作为实用设计和将来的指导天然土工布在各种可持续岩土工程应用中提高软弱地基的短期承载力的研究。
