城市隧道爆破施工的安全控制

The research on safety control of blasting construction of city tunnel

随着城市建设的快速发展,城市交通面临越来越大的压力,城市地铁的建设是解决城市交通拥堵的有效手段。由于造价低、拆迁少、无需太多专用设备及对地面交通和周围环境影响较小等特点,钻爆法被广泛地应用于城市地铁爆破开挖施工。随着爆破技术的广泛应用,开挖爆破对地表建(构)筑物产生的振动危害愈来愈受到人们的重视,如何将爆破振动灾害控制在最低程度已经成为工程和学术界越来越关注的问题。本文以城市隧道爆破施工管理为切入点,在阐述爆破施工安全控制的基础上,通过分析现状,重点归纳了城市隧道爆破施工的安全控制要点并提出建议。

With the rapid development of urban construction,urban traffic is/：acing more and more pressure.Urban subway construction is an effective way to solve urban traffic congestion.Drilling and blasting method is widely used in the construction of urban subway blasting excavation,because of low cost,less demolition,no need too many special equipment and the small impact on the ground traffic and the surrounding environment.Along with the wide application of＂ blasting technique, the harm of blasting on the surface construction is getting more and more attention.How to control the blasting vibration disaster to the lowest degree has become more and more concerned by the engineering and the academic field.Blasting construction management of urban tunnel is the breakthrough point of the article .This paper sums up the main points of the safety control of the city tunnel blasting construction and puts forward some suggestions,on the basis of blasting construction safety control and through analysis ofthe situation.
