2 D FEM analysis for an underground opening considering the strength anisotropy of the layered rock mass

More Information
  • Published Date: May 27, 1999
  • Because of the differences between the strength characteristics of the layered rock mass in parallel and perpendicular directions with respect to the bedding plane, the strength anisotropy must be considered in the nonlinear analysis. Basing on this consideration, the authors developed a 2 D no tension and elasto plastic FEM program, which can deal with the strength anisotropy of a layered rock mass. Some knowledge was achieved according to the calculated results of some examples.
