随着我国城市化水平的不断提高,城市交通压力越来越大。拥堵的交通现状要求必须要对地铁加以广泛应用。在地铁隧道开挖技术中,钻爆法是应用较为普遍的一种方法,它不仅不需要过多的专用设备,拆迁少,而且还具有经济性,对周围环境的影响小。目前,人们对爆破施工时地表产生的危害越来越重视,如何将开挖爆破的危害控制在最小范围内是急需研究的一个问题。本文对城市隧道爆破施工的安全控制进行了研究,希望具有借鉴意义。 With the continuous improvement of urbanization in our country, urban traffic pressure is getting bigger and bigger. Traffic congestion requirements must be widely applied to the subway. Drilling and blasting is a commonly used method in the tunneling technology of subway tunnels. It not only does not require too much special equipment, has less demolition, but also has economy and has little impact on the surrounding environment. At present, people pay more and more attention to the damage caused by the earth’s surface during blasting. How to control the damage of excavation and blasting within the minimum scope is an urgent problem to be studied. This article has carried on the research to the safety control of the urban tunnel blasting construction, hopes that has the reference meaning.
