Abstract

Taking the project of Hefei city plaza tunnel as an example, this paper takes the large-scale finite element calculation software of ABAQUS to set three dimensional calculations models to simulate the construction of underground tunnel, analyzing the displacement and stress dynamic response during the construction process. And the paper also carries out the comparison analysis of the field measurement of the land subsidence. The result indicates that the simulation objectively reflected the rules of subsidence during the construction process. This provides theory evidence for shallow-buried tunnel construction safely and rapidly.

Keywords: Land subsidence, energy numerical simulation, shallow-buried tunnel.
