Displacement Equations of Rock Surface under Rigid Plate Loading Test using Concrete Facing and their Applicability.

Abstract

Equations of vertical and horizontal displacements on a half space rock mass caused by a rigid plate loading test using concrete facing which restricts free horizontal displacements of the rock surface under direct contact with it, are developed. Young's modulus and Poisson's ratio of the intact rock mass can be simultaneously obtained by applying the equations to the test results.
