Abstract:
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.
