Abstract: Equivalent damage rheological model for jointed rock is preliminarily studied. Rock and jointed plane’s damage rheological functions are developed separately on the basis of supposing that the rock is isotropic body and isotropic damage and the jointed plane’s normal and tangential damage is different. Finite element method calculation function of equivalent damage rheological model for jointed rock is deduced; and its finite element method program is developed by assuming that the material is not damage and calculating stress adopting effective stress. Through case study, it is shown that the equivalent damage rheological model for jointed rock is feasible; it can reflect the damage process well.

Key words: jointed rock, damage, rheological
