摘要
采用二维弹塑性数值计算方法,对小净距隧道拱顶位移、水平收敛进行数值模拟计算,研究围岩级别、净距、开挖方法对隧道变形的影响,揭示小净距隧道洞周变形特征。研究结论可为小净距隧道的设计、施工提供一定的指导。
Applying 2 - D Elasto - plastic numerical calculation method and calculationning with numerical simulation for vault crown settlement and horizontal convergence, this paper studies the effects of rock classification, spacing , excavation method for deformation of tunnel and discloses deformation behavior of tunnels with small spacing. The result of the study provides guidance for design and construction of tunnels with small spacing.
