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 relevant 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 for subsequent design and construction.
