Two dimensional discontinuous deformation analysis

This paper explains a novel ‘back-analysis’ shceme to determine rock mass behaviour modes from an array of deformational measurements. The input will be the locations of data points and the set of measured displacements, as well as description of the locations and orientations of planes of discontinuity, and the blocks they determine. The output, drawn by the computer, will be the set of block displacements, rotations, and strains that determine the behavioural mode of the mass.
