Experimental study on dynamic response of underground utility tunnel under ground explosion

  • 摘要: 为研究地下综合管廊结构的抗外部爆炸性能,针对整体现浇管廊和预制节段拼装管廊结构在地面爆炸作用下的动力响应特性和破坏模式开展了野外爆炸实验研究。通过11个工况的野外爆炸实验,观测了现浇管廊和预制节段拼装管廊在不同比例距离爆炸工况下的破坏特征和动力响应,对比分析了现浇管廊和预制节段拼装管廊的抗爆性能。结果表明:在地面爆炸作用下,现浇管廊和预制节段拼装管廊的顶板最终均出现弯剪破坏,整体现浇管廊的抗爆性能总体上优于预制节段拼装管廊。起爆位置对预制节段拼装管廊爆炸响应的影响较大,在节段中心上方起爆时结构损伤最严重。在小比例距离地面爆炸作用下,现浇管廊的损伤区域大于预制节段拼装管廊,预制节段拼装管廊的损伤集中在近爆心下方所在的节段或连接接缝处,节段间可产生较大残余滑移。
