Testing rock mass deformability with large flat jacks

Abstract

Large scale rock-mass deformability testing was conducted in situ on several locations in Iran in order to define foundation possibilities for several structures. Test results and methods, involving the use of large flat jacks, are presented, and a critical overview on the interpretation of measurement results is given. The need to grout contact zones between the flat jack and the rock mass is explained. The relationship between the measured moduli of deformation, and the moduli determined by empirical limestone testing procedures, is defined.
