Aiming at the stability of surrounding rock and the selection of excavation scheme of shallow buried eccentric pressure tunnel in soft surrounding rock, Midas GTS NX was used to numerically simulate the construction process of Zhangshuya tunnel of Hunan Anci Expressway by middle pilot tunnel single side pilot tunnel method and three pilot tunnel method respectively. The stress and deformation of surrounding rock, the stress distribution of supporting structure and the stress of middle partition wall under different excavation schemes are analyzed. The results show that the two excavation schemes can meet the construction safety requirements. According to the actual situation of the tunnel, although the three pilot tunnel method can better control the settlement and deformation of the tunnel vault, the middle pilot tunnel single side pilot pit method is suitable for the construction scheme and its surrounding rock stress is excellent, which can better ensure the tunnel convergence and can effectively reduce the cracking of the middle partition wall waist on the deep buried side during the excavation of the shallow buried side. Moreover, the shallow buried side does not need internal support, which can accelerate the closure of the support structure and speed up the construction progress. Therefore, the method of middle guide tunnel and single side guide tunnel is a more suitable construction scheme for the tunnel. The research results can provide reference for other similar projects.
