Abstract: Abstract Strength reduction method and elastic-plastic FEM technique are reduced into RFPA codes. The RFPA code not only satisfies the global equilibrium, strain consistent and nonlinear constitutive relationship of rock and soil materials but also takes into account the heterogeneous characteristics of materials at mesoscopic and macroscopical level. As the proposed method is used to conduct the stability analysis of tunnel, the safety factor of tunnel is defined as the ratio of actual shear strength parameter to critical failure shear strength parameter. Not only the safety factor of tunnel with specific physics meaning can be obtained, but also the overall failure process and the location of failure surface may also be determined at the same time, so the present method is obviously superior to those traditional methods. The calculated results of a few engineering examples prove that the proposed method is effective in analyzing the stability of tunnel.
