摘 要：综述了近年来国内外关于滚石运动轨迹及滚石冲击力研究的新进展，介绍了滚石灾害风险评价与滚石防护措施的研究成果。现场试验、模型试验和数值模拟是目前应用较多的三种滚石运动轨迹研究的方法，其中数值模拟在滚石运动轨迹研究中已经成为主流研究手段。重点介绍了STONE, CRSP, RocFall三种滚石运动轨迹的数值模拟软件，列举了若干滚石冲击力的典型计算方法。最后进一步提出，在滚石运动轨迹研究中，数值模拟的发展应该侧重于滚石的滑动、自由落体、弹跳、滚动这四种运动状态之间的相互转化与组合机理的研究。

Abstract: This paper introduces the research development of rockfall trajectory and impact force in recent years. The development of rockfall risk assessment and prevention is also presented briefly in this paper. Field tests，model tests and numerical simulations are applied extensively in rockfall trajectory research nowadays, and numerical simulation has become the main research method. Three numerical simulation softwares: STONE, CRSP, RocFall are emphasized herein. Several rockfall impact force calculation methods are also enumerated in this paper. In future research, the transformation and combination of four types of rockfall motions, namely: sliding, free falling, bouncing and rolling should take into account in numerical simulation research on rockfall trajectory.
