高海拔Ⅴ级围岩长隧道安全高效施工技术研究

Study on Safe and Efficient Construction Technology of Ⅴ-Class Long Surrounding Rock Tunnel at High Altitude

隧道施工复杂度较高,遇高海拔地区时,施工难度会进一步加大。因此,如何在安全的前提下高效完成隧道施工作业,是值得重点探讨的话题。鉴于此,论文阐述了在挖掘隧道施工期间易出现的事故及原因,着重从安全技术和管理两个角度展开探讨,提出一些可实现安全高效施工的工程技术。

The complexity of tunnel construction is high, and the difficulty will be further increased in high altitude areas. Therefore, how to efficiently complete tunnel construction under the premise of safety is the topic worth focusing on. In view of this, this paper expounds the accidents and causes that are prone to occur during the excavation and vibration tunnel construction, and then discusses them from the perspectives of safety technology and management, and puts forward some engineering techniques that can achieve safe and efficient construction.
