Abstract: The stationcrossing technologies of TBM, including driving technology and stepping technology, are studied, so as to realize the synchronization of TBM crossing station and station construction. Special construction plans are made before construction, the structure types of the stations are optimized and the ground surface facilities and assistant equipments are transferred by using the intermediate stations. The following results have been achieved: 1) The TBM has crossed 6 stations successfully; 2) The rapid singledirection driving of the TBM is guaranteed; 3) The construction organization between the TBM tunneling and the station construction is well coordinated. 
