结合上跨正在运行地铁的南京红山南路隧道群钻爆法开挖工程,对上跨运行地铁最近距离为4.19m的钻爆法开挖工程进行爆破振动安全控制。通过建立爆破监督管理制度与信息化爆破振动监测等多种手段对爆破安全进行有效的管理,确保了正在运行地铁的安全。本文所总结的爆破管理经验对其他城市隧道开挖爆破管理具有借鉴作用。
Combined with tunnels excavation of Nanjing Hongshan South Road over the running subway by drilling and blasting method, blasting vibration safety control was carried out to excavation project which was 4.19m minimum distance to the running subway. Blasting safety was controlled effectively by a variety of methods such as establishing blasting supervision management system and information blasting vibration monitor, summarized can be which ensured the security of the running subway. Blasting management experiences used for reference to excavation blasting management of the tunnel in other cities.
