摘　　要：为保证大断面公路隧道在黄土层的施工安全,有效地控制变形,消除可能发生的隐患,以银昆高速公路南梁隧道施工为依托,通过分析两台阶法施工中变形数据的发展规律,总结了影响沉降变形的关键施工技术与维护围岩稳定的技术方法,并提出了相应的控制措施。从施工的效果来看,这些措施可确保隧道安全、优质、高效地完成,可供其他相似隧道施工借鉴。In order to ensure the construction safety of large-section highway tunnel in the loess layer,effectively control the deformation,and eliminate possible hidden dangers,based on the construction of the Nanliang Tunnel of the Yinkun Expressway,by analyzing the development law of the deformation data in the construction with the two-step method,the key construction techniques affecting sedimentation and deformation and the technical methods for maintaining the stability of surrounding rock are summarized,and corresponding control measures are proposed.From the perspective of the construction effect,these measures can ensure the safe,high-quality and efficient completion of the tunnel,which can be used as reference for other similar tunnel construction.
