| Abstract: | The elastoplastic finite element method is applied to simulate the excavation and reinforcement of Goupiyan diversion tunner in soft rock. The displacements and stresses of the surrounding rockmass after excavation are calculated. The effects of reinforcement and the stability of surrounding rockmass are evaluated. |
