CREEP AND RELAXATION OF 4 KINDS OF ROCK UNDER UNIAXIAL CIMPRESSION TESTS
单轴压缩条件下四种岩石的蠕变和松弛试验研究

The time-dependent behaviour of creep and relaxation of 4 kinds of rock are investi-gated under uniaxial eompression condition by using the servocontrolled hydraulic testingmachine. On the basis of discussion on the experimental curves of creep and relaxation andother time related deformation phenomena of rock specimen,the author provides the understanding and opinion about the rheological mechanism of the rocklike materials.
