The problem of shield machine driving through a station in Metro construction can be well solved by combining shield-driven tunnelling with mining or open cut excavation. Taking the starting 18.6 m of the San-yuanqiao Station of Beijing Metro Line 10 as the test section,the structure scheme of the Metro station adopting shield tunnelling and open cut methods was studied. According to the geographical position of the Sanyuanqiao Station and the design requirements of architectures and structures,4 kinds of station structures were designed including the pylon column station and vertical column station.Finally the 2.5 m side vertical column station was recommended. The special segment structure and joints of the segments with the main station structure,the key issues in structure design of a new Metro station,were studied in detail. The waterproof scheme of the station structure was also studied. The proposed Metro station structure scheme is in line with the level of the domestic shielding technology and economic strength. It has laid a good basis for follow-up researches.
