摘      要：The diverging tunnel is a new promising tunnel used in communication construction in West China, Aimed at the problems involved in excavation and research of the large-span and shallow part of Miaoya diverging tunnel in Hu-Rong Expressway, excavation mechanics simulation with FLAC3D is introduced and site monitoring is proceeded at Miaoya diverging tunnel. Based on the results, the excavation mechanics analysis and site monitoring of wall rock deformation and the mechanical character of supporting system are presented;some conclusion is drawn by the analysis of classical geology part of this tunnel. The research will devote to the following studies.
