摘要：This paper is based on the tunnels construction in small net distance in Jinan Rail Transit Line R3. The deformation of early mining tunnel when double-line shield tunneling under different net distance conditions is simulated. The results show that the late shield tunneling will cause the clearance convergence, vault settlement and inverted arch uplift of the early mining tunnel to further deformation. When the distance is 0.8 times of the tunnel diameter, reinforcement measures are needed.
