摘要 地铁地下结构作为重要的生命线工程,进行抗爆设计具有重要的意义,而我国在地铁地下结构应对突发性爆炸的防护技术方面研究起步晚,基础薄弱。在参考国内外地铁地下结构抗爆设计研究成果的基础上,阐述了需要亟待解决的四个问题:炸药爆炸当量估算方法和设防标准的确定,地铁地下结构内冲击波流场的研究,地铁地下结构内爆炸破坏效应模型建立及人员伤亡效应评估,地铁地下结构的抗爆设计和抗爆加固设计技术措施研究。这些问题的研究和解决将对新建地铁地下结构的抗爆设计和现有地铁结构抗爆加固技术措施提供坚实的理论基础。 Based on the analysis of anti-explosion design of underground subway structures at home and abroad, four issues should be seriously considered and urgently resolved: determination of the equivalence of detonator and resistance level, investigation on blast wave acting on underground subway structures, establishment of destruction model and evaluation of personnel casualty, anti-explosion design and reinforcement measures. The analysis and solution of these problems supply theoretical foundation of anti-explosion structural desgin and reinforcement for underground subway.
