摘要
介绍了单侧壁导坑法的工艺流程,通过对丘陵地貌区的城仔山隧道进行单侧壁开挖数值模拟,分析了洞周位移、超前管棚应力以及系统锚杆轴力随工序变化的曲线,探讨单侧壁导坑法在实际工程中的应用效果。
This paper introduces the process flow of single sidewall heading method.Through numerical simulation of single sidewall excavation of Chengzishan Tunnel in hilly landform area,the curves of the displacement around the tunnel,the stress of the leading pipe shed and the axial force of the system anchor rod are analyzed,and the application effect of single sidewall heading method in practical engineering is discussed.
