ABSTRACT
With the continued construction of the urban subway engineering, shield is increasingly used in the underground engineering; increasingly acute problems are met in the construction of neighboring tunnels. He Meide (2014) studied a certain largesection pedestrian upper passageway crossing the running shield tunnel of Beijing subway. The vertical displacements of shield tunnel structure, the horizontal convergence displacements of shield tunnel structure, and the vertical displacements of track bad structure were monitored and analyzed. The analysis result of this project shows that grouting from floor of passageway can significantly control upfloating, which can be applied in similar projects. On the basis of a constructing running shield tunnel subway side-through close to a high building (He Meide, 2010) using the finite-element method calculation model and site-monitoring method, the foundation characteristics of the high building affected by the constructing shield tunnel are studied. The settlements of the monitoring points reach the maximum value when the shield is 10.0 m away from the monitoring surface. The simulation and the site monitoring results agreed well. Through the analysis of the ground movement law
nonlinear finite element. Yamaguchi et al. (1998) summarized and analyzed the interaction of the four parallel tunnels near Tokyo from the angle of design and construction, respectively.
