纤维加筋土工程性能研究

Review of engineering performance of fiber-reinforced soil

纤维加筋土可以克服传统加筋土中存在软弱结构面的缺点,土和纤维混合,形成近似均质体的复合材料。研究结果显示,纤维加筋可以提高土体的强度,增加土体的延性,改善土体的工程性能。根据近些年国内外研究资料,分析了纤维加筋土的研究现状和研究成果,包括纤维的类型、土体的种类、研究的指标和研究的手段,并从工程应用的角度,提出了纤维加筋土下一步的研究目标,为后续的研究工作提供参考。

Compared with traditional reinforced soil, fiber reinforced soil is made by mixing fiber with soil, and the composite material can be seen as homogeneous material without weak structural plane. Results have shown that fiber can enhance the strength and ductility of the soil, and improve the engineering properties. In this paper, many recent research works were reviewed, and the research status and result were analyzed, including fiber styles, soil styles, research targets and methods. For engineering application, the next research targets were presented, and some references were offered in this paper.
