Abstract: Preliminary study on the collision of rolling stone and bridge pier was conducted by finite element method and the accidental head-on collision of the rolling stone with bridge pier was mainly analyzed． Based on the large structural analysis program，the dynamic response of bridge pier in the process of the collision was sutdied． The relationship among collision force，the rolling stone’s quality and speed was obtained．

Key words: rolling stone, bridge pier, collision, collision force

摘要： 利用有限元方法对滚石与桥墩的撞击进行了初步研究，重点分析了滚石与桥墩发生正碰的情况。运用大型 结构分析程序，研究了碰撞过程中桥墩的动力响应，得到了撞击力随滚石质量和速度的变化关系。
