| 摘 要： | 根据加筋方式的不同,纤维加筋可分为定向分布的纤维加筋和随机分布的纤维加筋两大类。本文针对这两类加筋方式,分别综述了纤维加筋技术在土体抗液化方面的相关研究进展,同时对纤维加筋土抗液化性能的主要影响因素进行了分析。既有针对纤维加筋土进行的动三轴试验、扭剪试验及模型试验等均表明,纤维加筋技术能有效地增强土体的抗液化强度,同时减小液化所引起的变形,是一种具有广泛应用前景的抗液化措施。

| Abstract: | Fiber reinforcement can be divided into two categories according to the different distribution forms of fibers ： one is that the fibers are distributed directionally within soil, and the other is that the fibers are distributed randomly within soil. This paper reviewed the researches progress of using these two kinds of fiber reinforcement technology to enhance soil liquefaction resistance. The main factors that influence the liquefaction-resistance characteristics of fiber reinforced soil were also analyzed. The existing research of cyclic triaxial tests, torsion shear tests and model tests about the fiber reinforced soil all indicate that fiber reinforcement can effectively enhance soil liquefaction resistance and reduce the deformation induced by liquefaction. Therefore, fiber reinforcement has a good prospect of being widely used to enhance soil liquefaction resistance. |
