摘要
纤维水泥土是在水泥土中均匀掺入纤维而形成的复合材料,其拥有良好的强度、韧性和抗形变能力.目前纤维水泥土静力性能的研究较为完善,但针对其动力性能的研究仍有不足,因此从动应力-动应变关系、动模量、阻尼比和动强度4个动力性能指标对现有纤维水泥土动力研究成果进行分析,并指出纤维水泥土动力性能研究存在的问题和不足之处,以期为未来高性能水泥土的发展提供借鉴.
Abstract
Fiber-reinforced cementitious composites are composite materials formed by uniformly incor-porating fibers into cementitious soil,possessing excellent strength,toughness,and deformation resistance.Currently,research on the static properties of fiber-reinforced cementitious composites is relatively well-de-veloped.However,there is still a lack of research on their dynamic properties.Therefore,the authors ana-lyze the existing research results on the dynamic properties of fiber-reinforced cementitious composites based on four dynamic performance indicators:dynamic stress-strain relationship,dynamic modulus,damping ratio,and dynamic strength.Finally,the problems and deficiencies research on the dynamic properties of fiber-reinforced cementitious composites are pointed out,aiming to provide reference for the future develop-ment of high-performance cementitious materials.
