摘要(Abstract):

浅埋暗挖型大断面隧道掘进爆破时,为避免盲目施工引发事故,对爆破参数进行优化是必要的。通过爆破参数试验和监测分析,对某城市地铁区间隧道进行爆破参数优化,既确保了施工进度和安全,又有效地保护了地表和地表建筑物
When a shallow large bore tunnel is drifted, it is necessary to optimize blasting parameters in order to avoid accidents due to blind blasting. In fact, through blasting test and survey analysis, optimization of blasting parameters of a city subway tunnel has been made, which not only ensure construction schedule and safety but also protect surface and surface structures.
