Abstract：
The waste management of plastic has become a pressing environmental issue, with polyethylene terephthalate (PET) being one of the major contributors. To address this challenge, the utilization of recycled PET fibers and strips in geotechnical engineering applications for soil stabilization has gained considerable attention. This review aims to provide a comprehensive study of the geotechnical engineering properties of recycled-PET-reinforced soils. The review examines various factors influencing the performance of PET-reinforced soils, including PET percent content, fiber length, and aspect ratio. It evaluates the mechanical properties, like shear strength, compressibility, bearing capacity, hydraulic behavior, and durability of recycled-PET-reinforced soils. The findings reveal PET reinforcement enhances shear strength, reduces settlement, and increases the bearing capacity and stability of the soil. However, it is observed that the incorporation of recycled PET fibers and strips does not lead to a significant impact on the dry density of the soil. Finally, an environmental and cost comparison analysis of recycled PET fibers and strips was conducted. This review serves as a valuable resource for researchers, engineers, and practitioners involved in the field, offering insights into the geotechnical properties of PET-reinforced soils and outlining future research directions to maximize their effectiveness and sustainability.
摘要：
塑料的废物管理已成为一个紧迫的环境问题，聚对苯二甲酸乙二醇酯(PET)是主要贡献者之一。为了应对这一挑战，在岩土工程应用中利用再生PET纤维和条带进行土壤稳定已引起相当大的关注。这篇综述旨在提供对再生PET加筋土的岩土工程特性的全面研究。这篇综述考察了影响PET加筋土性能的各种因素，包括PET百分含量,纤维长度,和纵横比。它评估机械性能，比如剪切强度，可压缩性,承载能力,水力行为，和耐久性的回收-PET-加筋土。研究结果表明，PET增强增强了剪切强度，减少沉降，提高了土体的承载力和稳定性。然而,据观察,再生PET纤维和条带的掺入不会对土壤的干密度产生显著影响。最后,对再生PET纤维和带材进行了环境和成本比较分析。这篇综述为研究人员提供了宝贵的资源，工程师,以及参与该领域的从业者，提供对PET加筋土的岩土特性的见解，并概述未来的研究方向，以最大限度地提高其有效性和可持续性。
