The purpose of this research is that the analytical solutions of non-linier behavior of ground in a deep circular tunnel under anisotropy stress field are derived, and the explicit analysis method (EAM) which bases on the convergence confinement method, the principle of confinement loss, and the simple calculation speadsheet is particulary proposed. This study includes that introducing a incremental procedure of confinement loss into the analytical solutions derived under anisotropy stress field, establishing the direct calculation logic and flow chart, using a calculation speadsheet to simply calculate and draw figures, considering the stress path and ground response curve at excavation face, and distribution of stress/displacement around tunnel.
