Theoretical stress distribution near explosively expanded rock bolt anchors
Investigation was made to determine theoretical stress distribution in vicinity of explosively expanded rock bolt anchors independent of their bolts; plane-strain solutions applicable to this problem were obtained by combining field pressure with uniform pressure that would be produced by vertically placed anchors having 2-, 3-, and 4-ft spacings; high rock stress which would be produced by anchor was localized, as would be expected from St. Venant's effect, and increased as field pressure decreased.
