## Ε½ . Three methods of in situ deformation modulus Em measurements of rock masses have been described, analysed and Ε½ . compared. The plate jacking PJT test, where the deformations are measured by extensometers in drill holes, gives generally the best results. A factor of 2.5 has been found betwee
