Abstract

Abstract

ANSYS, a finite element program, was used to analyze three typical cross-sections for the first stage of Shenzhen metro project, and the effects of different driving sequences and lining methods were investigated. The calculated result shows that the construction of the second tunnel has an effect on the constructed tunnel, the displacement and the plastic zone are different for different driving sequences, and it is better to drive the upper tunnel when the lower one has been driven. In addition, simultaneous lining is helpful for the control of surface subsidence
