随着我国社会经济水平的不断提升,全国各地的隧道工程建设也蓬勃开展,目前,我国大多数隧道工程的宽度都在12米以上,其具有埋藏深度浅、含水量高、断面大、围岩脆弱的特征,黄土隧道拱顶一般为砂层富水围岩结构,其施工难度较大、危险系数高,因此,在施工过程中必须重视对施工安全质量的管理和控制,本文就针对黄土隧道拱顶砂层富水围岩施工安全管控重点进行了分析和研究。 With the continuous improvement of social and economic level in our country, the construction of tunnel projects across the country is also booming. At present, most of the tunnel projects in our country are more than 12 meters in width with shallow buried depth, high water content, large cross-section, Therefore, it is necessary to pay attention to the management and control of the construction safety quality during the construction process. In this paper, we focus on the construction of loess tunnel The key points of construction safety control of water-rich surrounding rock in vault are analyzed and studied.
