摘要： 新奥法是目前广为采用的隧道动态监测施工技术。以石龙山隧道施工监测为例,详细说明了该技术在隧道施工中对围岩位移及受力变化的监控实施程序,并根据量测数据的分析处理对支护结构进行调整。实施结果表明,此方法能有效控制围岩的稳定性,节省支护费用,确保施工安全。

关键词: 隧道, 围岩, 监控量测, 回归分析

Abstract: New Austrian Tunneling Method (NATM) has been widely used in dynamic monitoring and controlling of Tunnel construction. Taking Shilongshan Tunnel construction as an example, the processes applying NATM to monitoring the surrounding rock deformation stability, stress variations and shoring control were detailedly presented. Some adjustment based on the analyses of measured data was maken. The results of the application indicates that the method is efficient in controlling the stability of the surrounding rock during the tunnel construction, and it cost effectively with improved construction safety.

Key words: tunnel, surrounding rock, monitoring and measurement, regression analysis
