Abstract This paper introduces the feasibility of the tunneling scheme and the ascertainment of the key position which affects the stability of engineering geologic body by numerical analysis of strain distribution of tunnel supporting. The corresponding reinforcement method is necessary for safe and economic construction of the tunnel.
