摘要:
为准确分析油气爆炸下隧道及采矿巷道等地下工程的结构稳定性,采用FLACS软件计算LPG爆炸荷载,基于LS-DYNA软件将爆炸冲击荷载施加于结构表面,进而计算爆炸荷载作用下衬砌结构动力响应。研究结果表明:隧道的“角状结构”对冲击波反射具有强化作用,致使相应位置形成应力集中,应力波强度衰减缓慢,随着传播距离的增加,衬砌所受应力逐渐减小且同一截面应力值趋于一致;同一截面不同测点处的速度、位移值受爆心距和隧道几何结构的共同影响,当爆心距大于12 m时,速度和位移值变化趋于稳定;顶部衬砌和底部结构更易发生破坏,边墙位置损伤程度较小。该研究成果为地下工程安全稳定性分析提供了方法依据,也为巷道抗爆设计及支护优化提供了理论参考。
