抄録

In nature, discontinuities in rock mass usually exist in the form of joint sets. In the paper, an analysis method for the effects of such discontinuities on the dynamic responses of rock mass is presented by imploying the conceptions of damage mechanics theory. A numerical scheme by finite element method has developed and used to reat the problem of elastic wave travelling in jointed rock mass. In addition, an elastic wave experimental program has been carried on the specimen of mortar with artificially made joints. It has shown that the dynamic responses computed by the numerical approach using the method presented are in good agreements with those obtained in the experiment, and the applicability of damage mechanics theory to the dynamic problems of rock mass has been confirmed.
