Abstract

Recently, the water environment, especially the investigation on the influence mechanism of high water pressure or water seepage on the tunnel stability is not thorough. In this study, based on the theory of seepage mechanics and elastic-plastic theory, the stress state of tunnel rock mass under the coupling of seepage field and stress field is analyzed, the formula for calculating the radius of plastic zone, the stress and displacement of the rock mass in the elastic-plastic state are derived. The stress and displacement of tunnel surrounding rock and the mechanical characteristics of the supporting structure are analyzed under the condition of seepage.
