Application of MIDAS GTS Analysis in the Excavation of a Shallow Buried Tunnel under the Unsymmetrical Pressure

Abstract

Abstract: This paper presents the finite element analysis results of the excavation progress of a shallow buried tunnel under the unsymmetrical pressure. The tunnel is part of the intercity of ChangshaZhuzhouXiangtan project in Hunan. The stressstrain properties of the surrounding rock mass and the deformation characteristics of the ground surface above the tunnel are studied. The analytical results are also compared with the observed data.

Key words: Shallow Buried Tunnels under Unsymmetrical Pressures, Tunnel, Tunnel Excavation, Center Diaphragm Method , Midas GTS Software.
