Abstract :
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 crown settlement of new tunnel and the existed tunnel, and the analysis on differential settlement between new tunnel and the existed tunnel.
