Deep foundation in the excavation process can lead to the deformation of surrounding surface. Because of the long excavation cycle and complex surrounding environment, it is important to monitor and control the deformation of surrounding surface subsidence. In this paper, combining the practice experience of surface subsidence control in the second stage of excavation project of Beijing urban rail transit control center, three-dimensional numerical analysis calculation model was established with ANSYS software. The calculation results tally basically with the measured data.
