摘要
以承秦高速某隧道为背景,通过FLAC3D数值模拟隧道开挖支护过程,与施工测量相结合分析其在开挖过程中的变化规律,研究在开挖过程中衬砌对隧道沉降及应力作用的影响。
The effects of factors on the stability of tunnels are various.Tunnel lining plays a very important role in long-term stability.With the background of a tunnel in Chen-qin highway,FLAC3D numerical software simulates the processes of tunnel excavation and support,combined with the measured data.The paper analyzes the changes and researches the influence on settlement and stress in the tunnel excavation.
