ROCK SLOPE REINFORCEMENT WITH PASSIVE ANCHORS
Untensioned, fully grouted, steel bars (dowels) up to 30 M long and 45 mm in diameter were used to reinforce rock slopes several hundred metres high, excavated for a hydroelectric project near Revelstoke, British Columbia. These dowels were successfully used to prevent surface rock from loosening, to prevent sliding on interconnected discontinuities and to prevent sliding of relatively intact rock on a thin shear zone. Because the interaction between rock slopes and dowels is not well understood, critical slopes were extensively monitored. Based on the experience from Revelstoke and elsewhere, it appears to be worth while, in most circumstances, to reconsider the need for tensioning rock anchors.
