Abstract

The elasto-plastic analysis of a circular tunnel excavation in layered rock medium using finite element method (FEM), the coupled finite element and boundary element method (FEBEM) is presented. The coupling procedure, the elasto-plastic formulation and application to the layered medium are discussed. The results of FEBEM analysis are compared with those obtained from FEM. The computation time and the number of iterations as required by FEBEM and FEM are compared. The effect of variation of modulus of elasticity on deformation, yielding and stresses is presented.
