The purpose of this paper is to study the effect of advance support on the stability of tunnel surrounding rock using the numerical analysis. For this, three different cases, such as without support, pipe shed grouting support, and advance small pipe grouting support were calculated and analyzed. The research shows that: both the pipe shed grouting support and advance small pipe grouting support all have a good effect on the supporting and strengthening of tunnel surrounding rocks. They can effectively control the vault settlement, haunch displacement, ground settlement and reduce the plastic zone distribution during tunnel excavation. In addition, compared with the advance small pipe grouting support, the pipe shed` grouting support has better effect on supporting and strengthening surrounding rock of tunnel. The study provides a reference for the actual engineering design of the tunnel.
