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%。
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.
