Abstract: 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.

Key words: fiber-reinforced soil, dynamic response, dynamic load, soil reinforcement
