Paper Title:
Scheme Comparison on Unsymmetrical Loading Tunnel Location near Tunnel Portal
  Abstract

In the process of tunnel excavation, due to the complexity of geological and geomorphic conditions etc, in the given tunnel heading shape conditions, it is more important to determine the tunnel location near tunnel portal. The large-scale finite numerical simulation software ANSYS is adopted to analyze that stress and displacement of tunnel surrounding rock vary with unsymmetrical location, including burial depth, slope angle and thickness of overburden layer. The analysis results show that: Under the condition of reinforcement in advance, it is proper for the tunnel excavation to reduce burial depth and thickness of overburden layer. This paper provides the theory basis for rational selection of support types and parameters and proper determination of tunnel location.
