The construction of the foundation pit that is close to a maglev line will lead to the deformation of this maglev line, and affect the safe operation. Based on the foundation pit construction of the underground station of Shanghai airport connecting line and the fire resistance experimental building of Shanghai Tongji University, this paper studies the influence of foundation pit construction on the deformation of adjacent maglev structure and its deformation development law. Through the arrangement of a variety of deformation monitoring points and the statistical analysis of a variety of monitoring data, this paper reveals the correlation between maglev structure deformation and foundation deformation which includes the deformation of underground continuous wall and deep soil deformation and so on, the key factors and methods that can effectively control maglev structure deformation are put forward. The research results have certain reference significance for follow-up similar projects.
