Abstract

Based on analyzing the damage feature of shallow buried and unsymmetrical loading tunnel, this paper studies the seismic reaction characteristics of this kind of tunnel via numerical simulation and comparison of the similar tunnel bearing symmetric load. The results indicate that the tunnel is more likely to get damage for its shallow bury ground and unsymmetrical load; there exists obvious acceleration amplification with the growth of the ground height, and this phenomenon is more significant on the ground surface; normally, the distribution of the lining cross-section’s internal forces is oval-shaped, while the unsymmetrical load makes the inner force nonuniform and leads to great inner force. It is great to recognize the seismic response characters of shallow tunnels through the study results and it provides reference for the similar projects.
