摘要
On the basis of Betti's theorem, the constitutive relation of multicrack rockmass which is applied to 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.
