摘要
随机离散纤维加筋是一种高效的土体改良技术,可显著提高土体在承受静、动荷载下的强度和变形特性。现有研究主要集中于纤维加筋土的静力力学特性,而纤维加筋土的动力响应特性未得到充分研究。纤维加筋土的动力响应特性对于工程构筑物在地震等动荷载下的稳定性具有重要意义。对现存的有关纤维加筋土动力响应特性的研究进行归纳、总结和评析,并基于此提出了有关纤维加筋土的动力响应特性未来研究方向的建议,以期为后续研究以及更好的将纤维加筋技术应用于工程实践作出贡献。
Soil reinforcement with randomly distributed discrete fibers is an efficient technology which can improve significantly the strength and deformation characteristics of soil subjected to static and dynamic loads.At present,existing studies are mainly concentrating on the responses of fiber-reinforced soil to static load,while the behaviors of fiber-reinforced soil under dynamic load are not well evaluated.Nevertheless,the dynamic responses of fiber-reinforced soil are very important to the stability of engineering structures subjecting to various kinds of dynamic loads,such as earthquake,sea wave,machine vibration,etc.In this paper,the current situation of existing researches upon dynamic behavior of soil reinforced with randomly distributed fibers is reviewed,summarized,and evaluated,based on which,suggestions on the future research work for dynamic behavior of fiber-reinforced soil are proposed,hoping for making a contribution to the subsequent researches and to better applying fiber reinforcement to geotechnical engineering.
