3D-FEM Stability Analysis of Fault Fractured Zone of Road Tunnel

Abstract:

In order to analyze the stability of the tunnel construction of the fault fracture zone, by adopting the three-dimensional finite element, the paper analyzed the construction process of the Qingshashan Tunnel passing through the F₅ fault fracture zone, and the rules and characteristics of deformation, stress distribution and its rules of changes, and the distribution range of the failure zone of the surrounding rock in the construction process, which would have important significance in guiding tunnel construction. Studies have shown that the three-dimensional finite element has a broad application prospect in tunnel projects.
