Combined with the engineering practice of small interval cross tunnel located at Shenzhen metro line 5 Taian ∼ Yijing road station, this paper points out a theory which contributes to guide the relevant construction by optimized means of construction scheme and numerical simulations. In addition, it details different construction methods of the small interval cross tunnel in water-rich stratum and...
Depending on the background of the civil air joint stage in Xizhimen subway station, this paper makes a numerical simulation on variable section conjugation engineering under complicated condition. The main contents are summarized below: (1) The analysis on stress changes of transitional structure. (2) The analysis on stress changes of the existed tunnel conjugation structure. (3) The analysis on...
