    • Abstract
  • Based on a deep foundation pit of metro in Beijing, the geological conditions of the proposed field, structural types and construction process are introduced. According to the monitoring results in the construction process, the variations of the displacement of fender piles, axial force of the steel supports and surface settlement are analyzed. The results of the numerical simulation are compared with those of finite element software, and they are almost consistent. Through further researches, the effects of pit size, embedded depth of the piles and construction condition on the deformation rules of deep foundation pit are obtained. It can provide a reference for the design and construction of deep foundation pits under this type of support.
