城市地铁岩石地层非爆破施工试验与应用

在地铁通过居民区、学校、医院等敏感区域时出于安全和减少扰民等要求,施工需要采取非爆破施工。文章以贵阳市轨道交通某项目为例介绍了钻劈台车和悬臂掘进机在地铁硬岩隧道施工中的试验和应用。分析了两种施工方法的优缺点,为类似工程积累了经验。

In order to meet the requirements of safety and reducing disturbance when the subway passes through sensitive areas such as residential areas,schools,hospitals and so on,non-blasting construction is needed.Taking a rail transit project in Guiyang City as an example,this paper introduces the test and application of drilling and splitting trolley and cantilever roadheader in the construction of subway hard rock tunnel.The advantages and disadvantages of the two construction methods are analyzed,which accumulates experience for similar projects.
