摘要
以天津软土地基小间距平行隧道为背景,在对实际加固方案分析基础上,采用有限元程序ABAQUS对小间距平行隧道掘进过程进行了动态模拟,分析不同加固方式和加固范围对先行隧道的影响,提出不同加固方式的影响规律与合理的加固范围,并分析盾构顶推力、隧道间距和地基土弹性模量等因素对先行隧道的影响。
This thesis takes the soft soil in Tianjin small spacing parallel tunnel as the background and on the basis of analyzing the actual reinforcement scheme, completed small spacing parallel tunnel excavation process dynamic simulation by using the finite element program ABAQUS. It analyzed the different ways of strengthening and reinforcement range influence on ahead of the tunnel and proposed reinforcement of the influence of different ways of reinforcing and reasonable reinforcing range. At the same time, it also describes the effect of jacking force shield, tunnel spacing and soil modulus of elasticity and other factors on first tunnel.
