The applications of sustainable and renewable materials have received considerable attention in geotechnical engineering. Soil reinforcement with plant-based fibers is a cost-efficient and eco-friendly process with high reproducibility and accessibility. The use of natural fibers as reinforcement elements is inherently distinct from synthetic materials, and the behavior of natural fiber soil is influenced by both physicomechanical and biological features. Reinforcing soil with plant-based or cellulosic fibers can be undertaken via two methods: oriented fiber distribution (OFD) and randomly distributed fiber (RDF). The latter process is the latest trend that has attracted increasing attention in soil reinforcement science. This study was undertaken to provide a deeper comprehension of the behavior of various plant-based or bio-based fibers and their properties, mechanisms, and functions as reinforcement materials for enhancing the mechanical strength of soil. The significance of the biochemical composition of natural fibers on their performance under reinforced soil circumstances is also determined. This paper also addresses key factors for extending the life of planetary fibers through various treatment methods, as well as reinforcement through bio-mediated technology, and finally discusses the future direction of fiber-soil reinforcement.

可持续和可再生材料的应用在岩土工程中受到了广泛关注。使用植物纤维进行土壤加固是一种具有成本效益和环保的工艺，具有很高的可重复性和可及性。使用天然纤维作为增强元件与合成材料有着本质的区别，天然纤维土壤的行为受物理力学和生物学特征的影响。可以通过两种方法使用植物纤维或纤维素纤维加固土壤：定向纤维分布 (OFD) 和随机分布纤维 (RDF)。后一种过程是最近的趋势，在土壤加固科学中引起了越来越多的关注。本研究旨在更深入地了解各种植物基或生物基纤维的行为及其作为增强土壤机械强度的增强材料的特性、机制和功能。还确定了天然纤维的生化成分对其在加固土壤环境下的性能的重要性。本文还探讨了通过各种处理方法延长行星纤维寿命的关键因素，以及通过生物介导技术进行加固，最后讨论了纤维-土壤加固的未来方向。还确定了天然纤维的生化成分对其在加固土壤环境下的性能的重要性。本文还探讨了通过各种处理方法延长行星纤维寿命的关键因素，以及通过生物介导技术进行加固，最后讨论了纤维-土壤加固的未来方向。还确定了天然纤维的生化成分对其在加固土壤环境下的性能的重要性。本文还探讨了通过各种处理方法延长行星纤维寿命的关键因素，以及通过生物介导技术进行加固，最后讨论了纤维-土壤加固的未来方向。
