| Abstract: | The rock support system for the powerhouse and transformer hall area of the Fljótsdalur Hydroelectric Project has been provisionally selected based, on one hand, on the boundary element method suggested by Hoek and Brown (1980); and, on the other hand, on finite element analysis, carried out with a program called STAUB (EWI Engineers and Consultants 1991). The analyses indicate that a combination of tendon cables, rockbolts and shotcrete will ensure the necessary redistribution of stresses and stability of the surface rock. Preliminary predictions of displacements are presented. |
