Abstract:
Whether the shield tunnel can be used in the ground fissure site is an issue in the metro construction and the structural adaptability and countermeasures are key points in Xi'an, China. Taking Xi'an Metro ring line(Metro Line 8)as the engineering background, based on field investigation, data collection, InSAR monitoring and finite element numerical simulation, the active trend of ground fissures in Xi'an and the classification of each ground fissure along Metro Line 8 were discussed, as well as the adaptability of shield tunnels with different assembly modes and section sizes in the ground fissure site was analyzed; finally, the countermeasures such as secondary lining and concealed beam, steel segment, grouting reinforcement, and local reinforcement of handholes were proposed, and the effectiveness was also validated. The results show that the shield tunnels can be used in Class Ⅳ sites with weak activity of ground fissure, and the staggered-joint assembly mode is better than the straight joint assembly mode for shield tunnel crossing the ground fissure zones, and the optimal diameter(D)of shield tunnel is 6.2 m; the longitudinal fortification length of sheild tunnel is 0.75D to 1.50D distance from ground fissure, which is related to the intersection angle between the tunnel and the ground fissure zones. The research can provide a scientific guidance for the structural design and disaster control of metro shield tunnel crossing ground fissure zones.
