Abstract:The elastoplastic 3D dynamic finite difference model was established by using FLAC3D numerical software. By fully con- sidering the inter-effect of the lining, the stratum and the ground, the influence of burial depth of tunnel on correlative dynamic response induced by metro operation was numerically simulated. The results show that, burial depth of tunnel induces significant influence on dynamic response of the lining, the stratum and the ground. The shallower the burial depth is, the severer the dynamic re- sponse is, and vice versa. For the lining-ring, different burial depth mainly results in different whole displacement response. For the stratum, the burial depth affects not only the intensity of dynamic response but also the range of affected region. It is a good way to reduce the noise and vibration on the ground by augmenting the burial depth of tunnel. The simulation results are conformed favorably with the site test.
