| Abstract: | In accordance with the practice of a certain pumped storage station's reinforced concrete bifurcation, the method of numerical simulation of materials such as surrounding rock, lining and so on is presented. And by using 3D linear and nonlinear FEM, stress analysis of rebar, lining and surrounding rock has made under different working conditions such as construction, internal water pressure and external water pressure. Some basic characteristics on loading and failure of the underground reinforced concrete bifurcation are discussed. |

| Keywords: | bifurcation lining surrounding rock FEM |
