In order to solve the stationcrossing problem for double shield TBM in the construction of urban rail transit tunnel, the doubleshield TBM construction of Qingdao Metro Line 2 is taken as the study background. According to the specific situation of the station where the TBM is based, combined with the construction conditions of the station and the impact of the TBM driving through station, two construction methods, i.e. empty push and movement are researched and implemented. A reasonable plan and key measures are formulated. The technical problems such as multiple disassembly, assembly, commissioning and the impact of the doubleshield TBM on the station are solved, which provides reference for double shield TBM construction of Qingdao metro line 1, line 4 and line 8 in the next stage.
Key words: Qingdao metro; doubleshield TBM; stationcrossing; empty push; movement
