| Abstract: | The Principle of damage mechanics is introduced into the researches of rock rheo- logy,and a damage evolution equation is proposed to describe the weakness of mech- anical properties of rock masses with time elapsing.The finite element formula are derived systematically.The checking computation result of in-situ monitoring data of a tunnel's deformation indicates that the model is reasonable and effective for thc numerical analysis of rock engineering. |
