Abstract

The construction of underground engineering will bring risks and potential hazards to the adjacent tunnel engineering. A series of numerical analysis models have been built to analyze the influence of underground engineering construction having on adjacent tunnel structure under different horizontal distance. According the simulation results, when the distance from underground space to tunnel is less than 10m, the interaction is fairly remarkable. It is suggested to take strong pre-consolidation measure during the construction of tunnel. The critical distance of underground space to adjacent tunnel is about 20m. When the distance is less than 20m, the adverse effect must be taken into consideration during the design and construction of adjacent tunnels.
