随者公路交通建设迅猛发展,为建设生态、低碳、环保公路交通,节约土地,建设安全和谐公路交通。穿越大山,公路隧道已普遍使用。但隧道建设施工,安全风险高,遇不良地质路段,安全风险极高,优选正确的施工方法,及时消除安全隐患,以确保隧道施工及后期运营安全。本文结合210国道陕西省镇巴县拴马岭隧道施工中发现的初期支护严重变形侵入二衬限界内安全隐患处理经验做简要分析。
With the rapid development of highway traffic construction, in order to build ecological, low-carbon, environmentally friendly road traffic, land conservation, construction of safe and harmonious road traffic. Through the mountains, road tunnels have been widely used. However, construction of tunnels with high safety risks and unfriendly geological sections will result in a very high safety risk. The correct construction methods should be used to eliminate potential safety problems in time to ensure tunnel construction and post-operational safety. In this paper, the 210 national highway Zhenba County, Shaanxi Province, tied to the Maling tunnel construction found in the initial support of the severe deformation of the invasion of the second line within the boundaries of security risks to do a brief analysis of the experience.
