摘　　要：大直径盾构隧道扩挖车站技术,能够充分发挥盾构施工速度快的优势,且对地面环境影响小,必将在今后的地铁建设中得到充分的应用。文章分析了大直径盾构隧道扩挖车站的优势,并通过建筑结构优化分析得出:单洞双线盾构隧道最小内径为8.8 m,双洞双线盾构隧道最大内径为7.5 m;同时对单洞双线和双洞双线盾构隧道扩挖车站进行了综合对比分析,结果表明,与单洞双线盾构相比,双洞双线盾构虽然造价低,但其空间有限,扩挖车站风险较大。The technology of large-diameter shield tunnel expanding excavation station can give full play to the advantages of fast shield construction, has little impact on the ground environment and will be fully applied in the future subway construction. This paper analyzes the advantages of large-diameter shield tunnel expanding excavation station.Through the optimization analysis of building structure, it is concluded that the minimum inner diameter of single-hole double-line shield tunnel is 8.8 m, and the maximum inner diameter of double-hole double-line shield tunnel is 7.5m. At the same time, a comprehensive comparative analysis of single-hole double-line shield tunnel and double-hole double-line shield tunnel expanding excavation station is carried out. The results show that compared with single-hole double-line shield, double-hole double-line shield has lower cost, but its space is limited and the risk of expanding excavation station is greater.
