Abstract：In order to solve the contradiction of construction time limit for running tunnel constructed by shield method and station in China，the new-style station construction method，in which the station is constructed by shield method and mining method，is put forward. In the model test study with scale ratio of 1∶10，the simulation of model stratum，excavation scheme and tunnel support scheme are introduced；and the station construction process is reappeared. The variation laws of strain，convergence of the shield segments and displacement of the soil around station tunnel are achieved. The results show that the excavation and tunnel support schemes can ensure the safety of the station under the conditions of model stratum and in-situ stress，by which the feasibility of station construction technology recommended is proved as well.
