Abstract

Abstract

By FLAC-3D, the whole process of excavation of big-span highway tunnel was simulated. Stress, deformation, plastic state of surrounding rocks at various phases were given. Stability of tunnel was evaluated. By the 3D simulation of excavation process, distribution of stresses and support can be known, influence on stability of surrounding rock in construction can be analyzed, and it can provide important references.
