摘　　要： 介绍颗粒阻尼技术基本概念、耗能机理及国内外应用与研究概况;系统阐述颗粒阻尼理论分析、数值模拟及试验研究发展,简述多自由度结构附加颗粒阻尼器离散元模拟方法;重点介绍颗粒阻尼技术应用于土木工程实例及相应研究,指出其在应用中的诸多优点及使用潜力,针对研究的难点与不足提出建议。 Basic concept, damping mechanism, application and studying status of particle damping technology were introduced. Its theoretical analysis, numerical simulations and experimental study developments were systematically presented. A discrete element method for simulating a multi-degree-of-freedom （MDOF） structure with a particle damper system was illustrated. The application of particle damping technology in civil engineering and its study situation were mainly discussed, its advantages and potential usages were demonstrated, the difficulties and deficiencies in the present studies were also indicated, and some suggestions were provided.
