Technical Schemes forM etro Station Construction Based on ShieldM ethod

The construction methods of overseas metro stations driven with the shield method were introduced. Based on the fact thata single-line shield tunnelhas a diameterofabout6. 0m in China, four construction schemes of ametro station driven from a sectional shield tunnelwith the expanding excavationwere 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 stationwere designed. Finally, the main related technical problems to be resolved were discussed, including construction steps, design method of station structure, design of special segmen,t environment control and project cost.
