In recent years, the construction of tunnels and subways has increased significantly. Current researches related to the underground engineering always focus on quasi-static force analysis of semi-infinite media, thus it is of great significance to analysis the borehole pressure during tunnel construction. In this paper, a finite cavity expansion model in finite diameter geological media is proposed considering the influence of finite radial extent of geological media and drilling velocity, and theoretical and computational analysis is carried out.
