摘　　要：纤维加筋土是一种新型体积补强技术,运用在路堤路基工程中时具有限制土体竖向和侧向变形,改善土体力学强度,增强边坡稳定性的作用。文章从静、动力特性试验和本构关系角度总结纤维加筋土应用研究成果,并对纤维加筋技术在道路交通工程中推广运用面临的关键问题进行分析,指出交通荷载条件下纤维加筋土动力变形特性的认知及如何将纤维材料对土体补强机制引入到土体的应力-应变本构关系式中是拓展纤维加筋技术在交通工程中发展潜能的两大关键理论课题。Fiber-reinforced soil is a new kind of bulk-reinforcement technology. When used in embankment or subgrade engineering, this technology could limit the vertical and lateral deformations of soil, and improve the mechanical strength of soil, and strengthen the slope stability. In this paper, a review of fiber-reinforced soil was given from aspects of the static and dynamic characteristic tests and constitutive relationship. The crucial problems were analyzed about promoting the application of fiber-reinforced soil in traffic engineering. The two crucial theoretical issues were pointed out about advancing this technology in the traffic engineering. First was properly recognized the fiber-reinforced soils＇dynamic deformation characteristics under the complicated traffic loads. The second was how to establish the stress-strain constitutive formula considering the fiber＇s mechanical reinforcement effect.
