Abstract

Abstract: The construction process of the Beilingshan Tunnel Section at Station D3K393+080 in the NanGuang Railway Project is numerically simulated by using the commercial finite element software ANASYS. The characteristics of this tunnel are the deep embedment, wide crosssection, and long alignment in the soft rock mass. The simulated deformation distributions are compared with the construction monitoring results. It is concluded that the simulated results are similar to the monitored values. Therefore, the design parameters selected for the analysis are reasonable and the analysis procedure can be used in the tunnel construction in the mountain areas.
