复杂浅埋地铁隧道微震爆破精细设计与控制研究

Study on Fine Design and Control of Microseismic Blasting in Complex Shallow Geological Tunnel

近些年,我国隧道建设进入高速发展阶段,其中浅埋隧道路段的开挖一直是个技术难题。虽然近些年我国对于浅埋隧道开挖技术有了进一步研究,但是与世界先进技术还有一定差距。隧道是我国目前主要的交通运输方式之一,关系着我国的经济命脉,尤其是城市地铁隧道有着其他运输工具不可替代的作用。本文基于微震爆破技术进行地铁隧道开挖研究,以期对该项技术的特点及控制要点有更加深刻的认识,从而为相关的地铁浅埋段施工提供有价值和有建设性的参考建议。

In recent years,China’s tunnel construction has entered the stage of vapid development,and the excavation of shallow tunnel section has always been a technical problem.Although there has been further research on Shallow Tunnel Excavation Technology in recent years,there is still a certain gap with the world’s advanced technology.Tunnel is one of the main modes of transportation in China.It is related to the economic lifeline of our country and plays an irreplaceable role in other means of transportation.In this paper,tunnel excavation is carried out based on microseismic blasting technology.Through the research and analysis of microseismic blasting technology in shallow tunnel,we have a deeper understanding of the characteristics and control points of this technology,and provide constructive suggestions for the construction of using this technology.
