An elasticity solution for the shear stiffness of the full-grouted resin roofbolt
SUMMARY The bolt is modeled as a beam on an elastic foundation where the theory of elasticity in polar coordinates is employed to determine the foundation modulus (spring stiffness) of the resin-rock combination. Parameter studies are presented showing the effects of the rock and resin elasticity on the shear stiffness values. The results obtained are compared to values obtained using a three-dimensional finite element study. The agreement between the elasticity solution and the three-dimensional finite element model is close enough to preclude the need for using the finite element model in this type of an analysis. © 1981, Elsevier Scientific Publishing Company.
