摘要: 大型越江隧道的抗爆能力是隧道防灾救援设计的重要内容。通过对三阳路越江隧道道路层及地铁层在爆炸作用下进行分析,采用静力荷载等效模拟爆炸荷载进行计算,得到了爆炸作用下的衬砌结构内力,结果表明管片衬砌结构承载安全并具有较大的承载冗余,内部结构局部节点需进一步加强。

Abstract: The blast resisting capacity of large rivercrossing tunnel is the key aspects of tunnel disaster prevention and emergency response design. The impact of blast from the road level and rail level of the Sanyang Road River Crossing Tunnel were simulated with equivalent static loading. The results suggest that tunnel lining has redundant structural capacity under blast loading, while the internal structure needs additional reinforcement at certain areas.
