Short summary
In Shanghai, China, land subsidence is distributed along the belt near a subway line. In order to figure out the mechanical response of the tunnel surroundings, the PFC2D software based on a discrete element method is introduced to simulate the section of the metro tunnel. The linear contact bond model was employed to reflect the characteristics of clay. The mechanical response law and subsidence mechanism were investigated.
