纤维加筋土是一种采用机械、水压或气压方式将纤维材料连续或离散地掺入到土中形成的具有优良工程力学性能的新型复合土。目前,纤维加筋技术已应用于挡土结构、路堤、水利水电、岩土工程等多个领域,所以,深入开展纤维加筋土的理论和工程应用的研究必将对推动我国未来土体补强技术产生深远影响。系统总结了纤维加筋土的强度特性、变形特性及渗透特性等工程特性的研究现状,阐述了近年来纤维加筋土的研究进展,并基于现阶段纤维加筋土的理论及技术研究方面的不足,对今后该领域的研究重点和发展方向进行了展望。
Fiber reinforced earth is a new type of composite soil with excellent engineering mechanical properties formed by the continuous or discrete incorporation of fiber materials into soil by mechanical, hydraulic or pneumatic means. At present, the technology of fiber reinforcement has been applied in many fields such as retaining structure, embankment, water conservancy and hydropower, geotechnical engineering and so on. Therefore, the research on the theory and engineering application of fiber reinforced earth in depth will surely promote the future Strong technology has a profound impact. The research status of engineering properties such as strength, deformation and infiltration properties of fiber reinforced earth are summarized systematically. The research progress of fiber reinforced earth in recent years is expounded. Based on the theory and technical research of fiber reinforced earth In the future, the research focus and development direction in this field are prospected.
