Abstract
This article uses nonlinear finite element (FEM) to analyses the mining tunnel surrounding rock mass through 3D model[1]. The study shows that the displacement and the stress of the surrounding rock of the main tunnel and branch tunnel increase with the embedding depth of the tunnel. The research also revealed the plastic zone, stress concentration areas and delamination transition of the stress.
