摘　　要：结合长沙地铁3号线阜埠河路站—书院路站区间工程,为确保盾构隧道安全穿越湘江溶洞区,通过优化具体设计方案,分别从线路平面设置,盾构机选型及设计,溶洞江面处理方案及施工工期方面进行探讨,提出合理的线路平面设计和溶洞江面处理方案,为后续设计及施工提供参考。In this paper, the project of Fubuhelu-Shuyuanlu section of Changsha Metro line 3 was taken as the research object. In order to ensure the safety of the shield tunnel passing through the carst cave zone of Xiangjiang River, the specific design scheme was optimized, and relewmt issues were discussed, including the route plane design, type selection and shield machine design, river surface treatment above the carst cave, and the construction period. Finally, the reasonable route plane design scheme and river surface treatment scheme were put forward in this paper, serving as reference tbr subsequent design and construction.
