Abstract: Taking Tongli elevator (Kunshan) circular deep excavation as an example, this paper presents the numerical simulation results using threedimensional finite difference software FLAC3D on the construction process of a deep excavation. The simulation considered the influence of both unconfined and confined groundwater, the coupling effect of dewatering on the deformation of the soil mass. The analytical results are compared with the observed data.
