The Effect of Model Scope on Numerical Results for Deep-Buried Tunnel

The numerical simulation method has become one of the most important assistant approaches for engineering design. But for the model scope of the overlying strata of deep-buried tunnel, there's no consensus which could be accepted by the whole geotechnical engineering industry; and, in most cases, the boundary of the model is determined by experience. In this paper, the influence of overlying strata' simulation on stress and deformation field of surrounding rock mass is studied through the 2D and 3D finite element method. The diameter, depth and section shape are all taken into account. Finally, a reasonable simulating scope of the overlying strata is proposed which may provide some reference for deep-buried tunnel's numerical simulation.
