EFFECT OF FLAWS ON THE STRENGTH OF ROCKS

Tests of uniaxial-compressive strength are carried out on cylindrical specimens of rocks including flaws. The distribution of strength is well interpreted, if one takes into consideration the angle of failure plane which is in most cases coincident with flaws. The quasi strength of rock mass defined as the product of the strength of fresh rock specimen and the square of the ratio between wave velocities in situ and in the specimen, is in good agreement with the strength of flaws determined in the tests.
