Revised Displacement Equations for Rock Mass Under Flexible Plate Loading Test Using Concrete Facing and their Applicability

Abstract

Equations of vertical and horizontal displacements in a half space rock foundation caused by aflexible plate loading test using concrete facing which restricts free horizontal displacements of the underlying rock surface, are developed. An optimal point of measurements for displacements in order to obtain Young's modulus and Poisson's ratio of the intact rock foundation is also discussed.
