摘要

On the basis of Betti's theorem, the constitutive relation of multicrack rockmass which considers the effect of crack-closure is developed in this paper.Meanwhile, based on mathematical elasticity, the paper gives an analytical formula for the compression transmitting coefficient and the shearing transmitting coefficient.A damage evolution equation of rock-mass is presented and an engineering application is given as well.
