摘　　要：近年来工程中大量使用纤维来对土体进行加固处理。纤维的掺入提高了土体力学强度,还能改善其变形特性。本文从纤维加筋固化土的实际需求出发,对纤维种类、掺量和长度等因素在加筋固化土中的作用进行了总结,同时从宏、微观角度对纤维加筋固化土的增强机制进行了分析,并介绍了纤维加筋固化土的变形特性和模型构建的研究现状。此外,还展望了该领域未来研究的发展趋势。In recent years,fibers have been widely used in engineering to reinforce soil.The incorporation of fibers enhances the mechanical strength of the soil and also improves its deformation characteristics.This paper,starting from the practical needs of fiber-reinforced stabilized soil,summarizes the roles of factors such as fiber type,content,and length in reinforced stabilized soil.It also analyzes the reinforcement mechanisms of fiber-reinforced stabilized soil from both macro and micro perspectives,and introduces the current state of research on the deformation characteristics and model construction of fiber-reinforced stabilized soil.The paper ends in a prospective discussion about the future trends in this research field.
