Technical Schemes for Metro Station Construction Based on Shield Method

The construction methods of overseas metro stations driven with the shield method were introduced. Based on the fact that a single line shield tunnel has a diameter of about 6.0 m in China, four construction schemes of a metro station driven from a sectional shield tunnel with the expanding excavation were proposed. According to the main technical standards and construction dimensions of Linhexilu station in the Guangzhou No.3 metro line, the structures and construction schemes of this station were designed. Finally, the main related technical problems to be resolved were discussed, including construction steps, design method of station structure, design of special segment, environment control and project cost.
