ROCK MECHANICS CONSIDERATIONS IN THE DESIGN OF CONCRETE DAMS
Common laboratory and field tests of rock masses are dealt with: the deformability and bearing capacity tests made by means of jacks inside galleries, triaxial tests of cylindrical samples subjected or unsubjected to lateral pressures, measurements of the speed of propagation of shocks, the "in situ" shear tests, the "in situ" permeability tests, and observations of internal stresses in the rock. Examples are given and discussed. Attention is paid to the influence of anisotropy, faults, joints and fissures, and of the degree of alteration. The dilatancy criterion of the strength is considered. The inaccuracy in the comparison of the strength as abtained by triaxial tests and either normal or inclined loading of the rock surface could be the cause of misunderstanding the term "strength."
