摘    要:为提高桥墩泥石流防撞墩的抗冲击性能,拟将废旧轮胎堆栈于防撞墩前,与之形成一种刚柔复合结构.并使用显式动力有限元软件LS-DYNA,通过对泥石流大石块的冲击过程进行数值计算,发现当冲击能量在轮胎的吸能范围时,其冲击力能降低80%.

关 键 词:防撞墩  废旧轮胎  冲击性能

Abstract:To improve the impact resistance,it is proposed that waste tires be stacked around the piers,forming a composite structure.Explicit dynamic finite element software LS-DYNA is used to calculate the impact process by large stones,and the result shows that the impact can be reduced by 80%when impact energy is within the absorption range of waste tires.
Keywords:crash-proof pier  waste tire  impact resistance
